Dead or alive 2 naomi rom

Post by footix » May 4th, 2015, 11:10 pm

Hello,

I have a doa2 cart that goes to black screen just after the naomi splash.

I can test all good in the rom test.

I also tried the trick to replace the P rom with the code from the netboot image.

All I get then is a rebooting cartridge after the splash... any ideas?

Thanks!

Arnaud

Faulty 16bit buffers. 90% of faulty carts are down to bad buffers.
