can't understand why there aint a layout of Cash Arena as dracula is just as old.....
Quite simple really, Ooh Aah Dracula is an MPU5 machine. MPU5 can't be emulated - no ifs, no buts. What happened is that BWB released a 'rebuild' of Ooh Aah Dracula for the seaside market, and Barcrest 'encoded' it for MPU4 technology.
We can emulate MPU4, hence we can emulate the BWB version of Ooa Aah Dracula. That is the only case I know of where BWB released an MPU4 version of an MPU5 machine, so no posting on and on about 'why no BWB Smokey Bikin, why no BWB Psycho Cash Beast' - They were released on the MPU5 and so cannot be emulated full stop.
What is possible, as was show by two designers on this site, Fruitymad2003 and Hurtand165, is that some machines in MPU5 have an MPU4 clone, albeit with different graphics. The one that they released was Psycho Cash Beast HDX, using the Psycho graphics, but the MPU4 Bangin Away roms. Aside from the sound, they play almost identically.
If I could get hold of some photos of Cash Arena - as long as it is a direct clone of Ooh Aah Dracula - I could make an HDX, using the graphics from Cash Arena [MPU5], but using the MPU4 ROMs from BWB Ooh Aah Dracula.
Hope that makes some deal of sense, there may be some bits in there you don't understand, in which case reply here and I'll try clear stuff up
