Re: Novag Delta-1 code
The MAME modification was to place the evaluation table at the right place without hacking the ROM. I didn't test it though.
The ROM hack is for the original hardware (or unmodified MAME driver). |

Franz, what hap posted is fine, it will do the same thing.
(Just copy that 64-bytes-table from ROM 0880-08bf to RAM 2bc0-2bff.) In the new eprom I put it at ECC0, but that will be 'mirrored' at 2XC0-2XFF.. The other bit in the first version I removed wasn't a computed goto as I thought, but would be used for the display and was correct (FE instead of FD). But it isn't called at all, so doesn't hurt. |

Aah, I think I'm understanding it now (your F8 assembly listing was Chinese for me.
![]() So you have added an extra code to copy this table to a different address, and hap's MAME change just remaps this 'wrong' table address to the correct place. But then hap's method and your ROM hack should have the same effect, right? If yes, then changing the mem map in MAME should be the simpler method, because you won't need an extra ROM file!? |

I let Boris rev1, Boris Diplomat and my modified Delta-1 solve this simple problem:

But which programmers. And have they been caught ?
The evidence is so obvious.
