I haven't tried any cartdrige games yet, Jipe, but nevermind, the problem is solved, we found a little piece of solder (is that the english name?) which was the source of all problems. Now my 8250 has a ROM from a Brazilian upgrade kit (AC88+), with boot logo and KANJI-ROM installed. Better than before, but still not complete, because of keyboard mapping.

But still I couldn't understand why the PLUSSUB2.ROM has 64 Kbytes, if the subrom only can have 32 Kb (2+).

you can remap the keyboard in the rom : start &HD9B

example :

AZERTY keyboard &HDBB &H71 (q) , &HDCB &H61 (a)

QWERTY keyboard &HDBB &H61 (a) , &HDCB &h71 (q)

normaly with the 64 eprom kanji mode is active but not kanji fonts

on your MSX type CALL KANJI0 (1,2,3) for new screen mode

CALL ANK for return to the normal screen

in kanji mode type :

COLOR 0 Return
COLOR 1 Return

test all key and see another mapping of the keyboard ( is japan keyboard )

Well, I should be able to edit ROM files, and save them using a EPROM recorder (what's the English name for a device like that?). But can I change it only using a POKE, like that? Thanks for the help, Jipe, I'll try them soon.
