Some of the instructions might be unclear!*\n\n## Custom menu builder for Sup Game Box 400-in-1. Requires actual ROM image!\n\nTo successfully build the menu, you need to get some knowledge on how the unit works etc: [article](https://nyh-workshop.github.io/Custom-ROM-Sup-Game-Box-400in1/).\n\n![image](https://github.com/user-attachments/assets/5a8df030-2f2d-4d86-8eb2-b139600e546e)\n\n### You also need these:\n- [CC65](https://cc65.github.io/) installed and path set.\n- Getting this [template menu](https://github.com/nyh-workshop/CustomMenu_Sup400in1).\n- (For Manual Entry only!) The [OneBusCalc](https://github.com/nyh-workshop/OneBusCalc) to calculate the OneBus registers for the system to jump to the appropriate address.\n- and finally, this app.\n\n### Directions for Automatic Entry (currently only Mapper 0 games supported):\n- Run this menu builder app. Supply the template menu folder link into the \"Build Folder\".\n- Add NES games (**only Mapper 0 games supported now on automatic entry!**) inside by pressing **Add Item**. You can move items up and down in the list!\n- Just click on \"Auto Populate OneBus\" to automatically calculate the CHR, PRG addresses and the OneBus registers! No need to do other things!\n- Finally, press \"Compile\". When it is successful, go to the cmd and run \"make\". The make will compile the menu, and combine the apps into the main binary.\n- Run this output_final.bin with an emulator such as EmuVT 1.36.\n- You can save the games list into the **CSV file**, or you can load them too!\n\n### Directions For Manual Entry:\n- Run this menu builder app. Supply the template menu folder link into the \"Build Folder\".\n- Add NES games (**only Mapper 0 and MMC3 games supported now!**) inside by pressing **Add Item**. You can move items up and down in the list! \n- With your OneBusCalc, determine the start PRG and CHR addresses. Make sure it is from **0x90000 onwards** because 0x80000-0x8FFFF is the custom menu code!\n- Also, with the OneBusCalc, adjust the values of these \"PRG and CHR Registers\" accordingly. Once you are satisfied with it, click on \"Generate Code\".\n- From the OneBusCalc, after \"Generate Code\", copy and paste the bottom output **without the square brackets** into the Menu Builder's \"Config OneBus\" entry box.\n- Finally, press \"Compile\". When it is successful, go to the cmd and run \"make\". The make will compile the menu, and combine the apps into the main binary.\n- Run this output_final.bin with an emulator such as EmuVT 1.36.\n- You can save the games list into the **CSV file**, or you can load them too!\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnyh-workshop%2Fmenubuilder_supgamebox","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnyh-workshop%2Fmenubuilder_supgamebox","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnyh-workshop%2Fmenubuilder_supgamebox/lists"}
