[0035] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, below, the technical scheme in the utility model embodiment will be clearly and completely described with the drawings in the utility model embodiment, obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiment.Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making the creative labor all belong to the range of protection of the utility model.

[0036] The retro game equipment or palm game machine equipment of the 80s to 90s of last century as a kind of game trend has begun to be popular again. The current retro game machine equipment is the SoC development board such as raspberry pi etc. as its core motherboard using running Linux system, burns Linux system in SD card etc. start medium, and copies emulator program to SD card, powers on the SoC development board, and then starts emulator program through self-starting script.

[0037] But the current retro game machine equipment has the following shortcomings:

[0038] A. The SoC development board with strong performance needs to be used, and the cost is high;

[0039] B. Since the SoC development board needs to execute the Linux operating system first and then execute the emulator program, the starting time is long;

[0040] C. At present, the system, emulator program and ROM of the retro game console device based on the SoC development board are seriously dependent on the SD card storage, and the reliability is not high. Unexpected power failure can easily cause the SD card file system to be damaged, thereby causing the Linux system to be unable to start normally and other problems, resulting in that the game console function cannot be normally used;

[0041] D. The retro game console device needs to update the entire Linux system and the emulator program respectively when updating the system, and the steps are long and tedious, usually need to borrow a PC to burn the Linux image, and the user operation requirement threshold is high;

[0042] E. The secondary development of the retro game console device needs to consider the driver adaptation of the Linux system, and the related driver code is mostly closed source implementation, and it is difficult for users to develop by themselves;

[0043] F. The use scene is single, and it can usually be used only as an emulator host.

[0044] G. It does not support reading the original game console tape.

[0045] As can be seen, the current design of the retro game console device cannot adapt to the current game environment, and cannot better meet the game needs of users. How to design a retro game and device that meets the current game industry needs is an important problem to be solved in the industry at present.

[0046] In order to solve the above problems, a multi-form retro game console device is provided in the specification, which can be understood as. Please refer to Figure 1 and Figure 2 The retro game console device specifically includes:

[0047] The main board component 10 (Console PCBA) based on FPGA, the system on chip 20 and the access memory 30.

[0048] The mainboard assembly 10 is provided with a memory card slot for inserting a memory card and a cartridge expansion slot for connecting a cartridge expansion module. It can be understood that the memory card slot is used for inserting a memory card, the cartridge expansion module is used for inserting a cartridge, and the mainboard assembly 10 is further provided with a key expansion slot for connecting a handheld game console key expansion module and a plurality of handle expansion slots for connecting handles. When the mainboard assembly 10 is connected with the handles and the handheld game console key expansion module, the retro game console device is in a handheld game console mode, and when the mainboard assembly is not connected with the handles and the handheld game console key expansion module, the retro game console device is in a host computer mode, and can also be used as a PCIe HAT expansion card of the system-level chip 20.

[0049] In the embodiment, the mainboard assembly adopts a Console Printed Circuit Board Assembly (PCBA). The Console Printed Circuit Board Assembly is a mainboard assembly (PCBA) for a game console. Correspondingly, the mainboard assembly 10 is provided with a set of Board-to-Board (BTB) connectors for a circuit board cooperating with an FPGA SOM, a FPGA debugger, a PGA analog USB connection port, an HDMI output connector, an SD card connector, and a plurality of function keys, pin expansion connectors, standard PMOD connectors, lithium battery charging and discharging management circuits, and power amplifier circuits according to requirements. Meanwhile, a host computer shell is used as a whole carrier in the retro game console device. The mainboard assembly is assembled in the interior of the host computer shell.

[0050] Assembly, PCBA). The Console Printed Circuit Board Assembly is a mainboard assembly (PCBA) for a game console. Correspondingly, the mainboard assembly 10 is provided with a set of Board-to-Board (BTB) connectors for a circuit board cooperating with an FPGA SOM, a FPGA debugger, a PGA analog USB connection port, an HDMI output connector, an SD card connector, and a plurality of function keys, pin expansion connectors, standard PMOD connectors, lithium battery charging and discharging management circuits, and power amplifier circuits according to requirements. Meanwhile, a host computer shell is used as a whole carrier in the retro game console device. The mainboard assembly is assembled in the interior of the host computer shell.

[0051] Meanwhile, the mainboard assembly 10 is provided with a system-level module (FPGA SOM) composed of an independent PCBA, including an FPGA, an FPGA peripheral circuit for connecting the BTB connector of the Console PCBA, and a Flash module. In this way, the mainboard assembly 10 uses a nor flash solidification simulator program, so that the memory card only serves as a ROM storage device, and the retro game console device itself will not be damaged in case of unexpected power failure.

[0052] Specifically, the cartridge expansion module is composed of two independent PCBAs. The cartridge expansion module allows users to directly insert and use original game console cartridges.

[0053] The system on chip (SOC) is electrically connected with the mainboard component 10. The SOC of the retro game machine device uses a Raspberry Pi computer mainboard, and connects the Raspberry Pi computer mainboard and the mainboard component (Console PCBA) through the same FPC connecting line. In this way, the mainboard component can be used as a PCIe HAT expansion of the Raspberry Pi.

[0054] The access memory 30 is electrically connected with the mainboard component. Considering the current game environment, in order to shorten the start-up time of the emulator and greatly reduce the waiting time of the user, in the embodiment, the access memory 30 adopts a synchronous dynamic random-access memory (SDRAM), and the mainboard component 10 is provided with a memory expansion slot for inserting the access memory. It can be understood that the access memory is electrically connected with the mainboard component through the memory expansion slot, and the memory expansion slot is used to connect the pin expansion connector in the mainboard component (Console PCBA), so as to realize the expansion of the SDRAM memory. In this way, part of the emulator can use the SDRAM memory,

[0055] Please refer to Figures 3 to 13 The mainboard component 10 uses a stable and reliable BL616C-50-Q2I chip as the core element of the USB-to-FPGA debugger circuit, which can cooperate with the upper computer to burn the firmware of the FPGA and enter the test mode. The core of the entire debugger is composed of only the BL616C-50-Q2I single chip. The periphery is only composed of resistors, capacitors and an inductor. Through such a setting, not only the cost can be effectively reduced, but also the complexity of the system is reduced.

[0056] The BL616C-50-Q2I chip running the above-mentioned components can realize all the functions of the debugger. Among them, SW3 and its peripheral circuit are the download circuit of the BL616C-50-Q2I chip. Its function is to make the BL616C-50-Q2I chip enter the DFU mode after being pressed, so as to burn the corresponding firmware into the BL616C-50-Q2I chip; J21 is a USB-C interface, which is used as the USB debugging interface of the mainboard component 10 in normal times, and is used as the USB burning interface of the BL616C-50-Q2I chip when the BL616C-50-Q2I chip enters the DFU mode; the two signal lines of DBG_TWI are the I 2 C interface of the debugger as the HOST, which can be used to expand the I 2 C slave of the debugger to enrich the functions of the debugger.

[0057] It should be noted that all external interfaces in the debugging interface circuit are designed with ESD protection measures to improve the stability of the system. Through such a setting, the retro game machine device has a firmware update function, and users can complete system updates without the help of a host computer. Of course, the mainboard assembly 10 is provided with a debugger interface, and the retro game machine device is electrically connected with the host computer through the debugger interface, that is, the mainboard assembly 10 can also be connected with the host computer through the debugging interface circuit, and the host computer is used to perform corresponding update operation on the retro game machine device.

[0058] The mainboard assembly 10 is provided with a first display connector, which is used to connect a display device matched with the retro game machine device. The display device can be understood as a display screen provided with the retro game machine. Specifically, the mainboard assembly 10 is provided with a standard RGB display screen connector and a corresponding display screen backlight boost circuit, which can support the connection of a matched RGB display screen for use, so as to meet the product use in a palm scene.

[0059] Meanwhile, the mainboard assembly 20 is also provided with a second display connector, which is used to connect a display device independent of the retro game machine device. In the embodiment, the second display connector adopts an HMDI output circuit, which supports 1080P and 60Hz image output, and is compatible with most display screens and televisions on the market. Through such a setting, it is convenient for users to directly connect a television or a display screen for use. The HMDI output circuit mainly realizes AC coupling by taking the LVDS signal transmitted by the HDMI as the Source end and the SINK end (usually a display screen or a television) of the HDMI, wherein the 499R / 1% pull-down resistor between the coupling capacitor and the HDMI connector is a resistor cooperating with the 50Ω pull-up of the HDMI SINK end to realize a 10:11 voltage division, so that the common-mode voltage of the differential signal output on the HDMI interface is 3.0V to meet the specification requirements of the HDMI.

[0060] The HMDI output circuit contains complete HDMI DDC communication implementation. The HDMI_DDC.CLK and HDMI_DDC.DAT two signal lines are responsible for realizing the DDC communication of the HDMI. Q4 is an I2C level conversion circuit, which is used to convert the level of the DDC communication of the HDMI from 5V to 3.3V level which can be received by the FPGA.

[0061] The HMDI output circuit also contains HDMI HPD (hot plug), which is composed of a voltage division network composed of two resistors R53 and R127, which is used to divide the 5V high-level HDMI HPD signal to 3.3V high-level signal which can be received by the FPGA.

[0062] Wherein, the role of Q11 is to close all pull-down resistors to achieve low power consumption when the HMDI output circuit does not transmit signals. Q11 is controlled on-off via DVI-A_PSV signal; U3, U4, U5 are ESD protection devices, which can effectively avoid damage of related circuits caused by ESD problems, and improve the reliability of the system.

[0063] The USB circuit in the mainboard assembly realizes the USB1.1 HOST mode and the USB3.0 slave mode, wherein the USB1.1 HOST mode can be used for connecting a USB handle controller, and the USB3.0 slave mode can be used for taking the device as a PC expansion module, such as a UVC acquisition card, so that the user can also obtain the running picture of the emulator host through USB connection when there is no HDMI display.

[0064] The mainboard assembly 10 has a plurality of external connector interfaces, wherein J9 and J10 can be connected with SDRAM expansion modules or card tape expansion modules at will. J6 and J7 can be connected with standard PMOD expansion modules. J6 and J7 are on the same side of the mainboard assembly, and therefore can also be compatible with the Dual-PMOD expansion module on the market. The ADC INPUT utilizes the ADC of the FPGA itself to realize detection of the battery voltage and the VBUS voltage of the mainboard assembly, and only needs a resistance-capacitance network to realize detection of the above-mentioned voltages, so that the mainboard assembly can be used as a retro game console and also has the possibility of being modified into a battery-powered handheld game console.

[0065] The RPI HAT PCIe circuit of the mainboard assembly 10 realizes an FPC connector compatible with the Raspberry Pi PCIe connector, so that the mainboard assembly has the ability to be used as a PCIe HAT expansion card of the Raspberry Pi.

[0066] The multi-form expanded retro game console device of the utility model uses the mainboard assembly 10 based on FPGA, saves the overall cost, uses SDRAM for the access memory 30, shortens the start-up time of the emulator, greatly reduces the user waiting time, and since the card tape is inserted into the card tape expansion module, the card tape and the card tape expansion module are assembled into a card tape carrying a game, so that the retro game console device supports reading the card tape of the original game console, and the retro game console device can easily convert into various forms, is in the form of a host computer at ordinary times, can also be expanded into a handheld game console by inserting a handle module, and can also be used as a PCIe HAT expansion card of the Raspberry Pi, so that the utility model provides a retro game console device with high reliability, economy, feasibility and high degree of freedom, which can well realize the function of a retro game console, is convenient for users to maintain and repair, and is also convenient for R&D personnel to modify and optimize.
