64KB ROM flash cartridge

64KB Flash Cartridge for MSX.

It is written directly from the MSX without the need for additional hardware.

To write a ROM, all you need is the software simplefw.com created by V9938. You can download it from their GitHub.

The usage is very simple:

1. With the MSX turned off, insert the 64KB flash WITHOUT the jumper into one of the slots.
2. Once the MSX is powered on, place the jumper to activate the cartridge.
3. Run the command:
   simplefw.com [ROM File] (/0,4,8)
4. Your ROM will be written to the cartridge.

For example:
simplefw.com myROM.rom /0

The options (/0,4,8) are:

/0 : Write the ROM file starting from address 0x0000 (for 64KB ROMs)
/4 : Write the ROM file starting from address 0x4000 (for 48KB ROMs)
/8 : Write the ROM file starting from address 0x8000 (for 32KB ROMs)
