i have cleanly emerged generator-gtk , but , when i tried to load some romes it generates [CRIT] errors like :

[CRIT ] 00000000 [ROM] Invalid memory store (word) 0x32552 = 0
[CRIT ] 00000000 [MEM] Invalid memory store (long) 0x6B9006 = 76
[CRIT ] 00000000 [MEM] Invalid memory store (word) 0x6B9004 = 2004
[CRIT ] 00000000 [ROM] Invalid memory fetch (word) 0x325CB
[CRIT ] 00000000 [ROM] Invalid memory store (word) 0x325CB = 0
[CRIT ] 00000000 [ROM] Invalid memory store (word) 0x32554 = 0
[CRIT ] 00000000 [MEM] Invalid memory store (long) 0x6B9000 = 76


finaly it crashes ..

is it 64bit problem ?

but why does it compile then okay .. ?
sega was 16 . wasn't it ?

That's either a damaged ROM or bugs in the game. If I remember correctly, you contacted me per mail and this was a compressed ROM. After loading a ROM, Generator shows a message with the game title on the terminal. If that looks bogus, the ROM is most-likely damaged or if you used my patched version, the compression might have failed. Try to extract the ROM manually and load the uncompressed file instead.

Also for AMD64, make sure that you pass --with-cmz80 to configure. The setting --with-raze will not work for AMD64 even though it compiles. It's for x86 only and nothing else.
