Hi friends,
I've tried the ROM2COM utility, downloaded from msx.org, with konamy soccer rom.
Command I've used is:
rom2com soccer.rom
in MSX-DOS 1 environment under MSX-PLAYer.
But... soccer.com doesn't start, only copyright string displayed.
Does the utility work only with real MSXs?
Can you help me?
Thank you,
Enrico

The utility does work, but only with a small percentage of ROM files. Try and see if you can get another ROM file working.

If you use with originals roms this programm don't work because this roms have copy-protection, write in his own code, so you can't use originals roms. You need roms modified (for example all roms modified for loadrom, that this copy protection was removed).
It is not a ROM2COM fail, is protection of konami roms.

The utility works with almost every ROM <= 32KB. I tested it with hundreds of ROMs and it worked in a high percentage of cases.
The problem is related to copy-protection inside original ROMS. Konami protected the ROM games by making some self-modifying. If the game is loaded in RAM (.COM are loaded in RAM), then it doesn't work.
Ih that cases a cracked .ROM is needed. Well, OK, I could try to recognize the game at loading-time and to patch it. But I made this utility in a couple of hours and I didn't think of patching specific ROMs .....
Maybe in a new version I could add this feature.
