Hmm, sanni, would it be best for the SD card to have no other files besides all the required files and the save files I want to copy to the various cartridges I might use the cart reader with. You can also try out a different SD card. Make sure the N64 carts are plugged in perfectly centered, that the voltage is 3.3V and that the n64.txt was copied to the SD card. Output.CartridgeType = (byte)Data.ReadByte() Public static ROM ParseROM(MemoryStream Data, String File = null)ĭialogResult dialogResult = MessageBox.Show("Press yes for hiROM and no for loROM", "Select ROM type", MessageBoxButtons.YesNo) Įlse if (dialogResult = DialogResult.No) I have made a small code change to the SF Memory Binary Maker that lets you manually select HiRom/LoRom since some roms get the wrong type assigned sometimes. Next you'll need to download and start SF Memory Binary Maker to create the mapping and the combined menu/rom file. I wrote a small program that splits the NP file automatically or you can split it manually using a hex editor. In this case you need to extract the menu from your NP backup, it's the first 512KB of the 4MB file. If the sum of your roms does not exceed 3.5MByte you can flash multiple roms including the menu. Your NP cart should now act as if it was a Chrono Trigger cartridge. In this case just flash the translated Chrono Trigger rom and then flash the hirom64.map file. So for a 4MB like Chrono Trigger you can't have a menu, just the game. The NP cart has 4MByte, the menu needs 512KByte of that. So the first thing to do is to check your roms with a program like NSRT and if needed fix the checksum with Snes Rom Checksum Fixer. They also can't have an emulation/copy station header. All roms need to have valid checksums or they won't launch.
