MAME Info:

0.114u1 [Guru]


- 0.144u7: Arzeno Fabrice added clone Virtua NBA (prototype).

- 0.143u4: Added virnbao-key.bin rom to clone Virtua NBA (JPN, USA, EXP, KOR, AUS) (original).

- 0.131: Guru added clone Virtua NBA (JPN, USA, EXP, KOR, AUS) (original). Added missing user1 roms.

- 20th April 2008: Guru - Thanks to some info from Deunan Knute (author of Makaron) I was able to get the ROM cart for Virtua NBA that I just dumped working in-game! The emulation crashes pretty early though, might be emulation or protection issues causing that. But this is pretty amazing considering this game was not dumped when the emulator was written. Thanks again to Deunan Knute for the info! Just bear in mind that there was no special magic involved here. The ROM loading just needs to be correct. As I said below, the ROM carts will not work in Makaron if the security chip is present, and currently only 3 games don't use it. There's no point trying to get the other games working because they will not work unless the security is either emulated or patched out and neither of those are done by the current version of Makaron. I've been messing around with Makaron again and ROM carts. While checking some things I realised what was going on. It seems it's not all that difficult to get a NAOMI ROM cart to boot but there's one big factor involved. The cart must not have the 317-xxxx security chip in it. Unfortunately only 3 NAOMI carts I know of documented on my NAOMI page don't use the security chip. They are Sega Marine Fishing, Virtua NBA and Typing Of The Dead. It's a HUGE credit to the Makaron author that the emulator is so versatile, even in this early stage of development. To get a cart running simply do a binary copy of all of the ROMs and make one big file, starting at IC22 and then IC1, IC2, IC3 etc. And here's a few pics of some carts I dumped to show that it's possible. They don't go in-game yet. However they will go into TEST mode. Virtua NBA NAOMI cart arrived from Japan a couple of days ago.

- 18th April 2009: Guru - I've been doing more dumping today and dumped a few more NAOMI carts including Virtua NBA.

- 0.114u1: Guru added Virtua NBA (JPN, USA, EXP, KOR, AUS) (Sega 2000).
