Downloads

System requirements

• MSX, MSX2, MSX2+ or MSX turboR
• 128K main RAM
• 16K video RAM
• MSX-DOS 2

Usage instructions

Run ASCIIXF from MSX-DOS 2, specifying the ROM file to flash on the command line.

Warning: Make sure to have a means to bypass booting the ROM so you can get back to MSX-DOS2 to erase the cartridge. E.g. by implementing a boot bypass key in your ROM, by using a slot expander with slot disable switches, or using Nyyrikki’s Boot Manager.

Usage:

asciixf [options] <file.rom>

Options:

• /s Slot number (required). Format: p or p-s.

• /e Erase flash ROM.

• /p Program flash ROM from file.

• /v Verify flash ROM with file.

• /d Dump flash ROM to file.

• /i Display flash ROM information.

Example:

asciixf /s2 /e /p /v example.rom

This erases, programs and verifies a ROM to the ASCII-X cartridge in slot 2.
