Fixed B-Wings mapper (185).

Jungle Book is in my list of defective games. I am assuming it is a mapper problem (MMC3 IRQs). Very unlikely it is a NES core problem.

MMC3 IRQ support is slightly incomplete, with most games running. The only setback is keeping the speed up on the PS2 port while implementing a proper MMC3 IRQ system. It will be worked on in the near future.

i have tried a few games in your list that i have found to be working, and i cannot reproduce the same errors.

Willow (U).nes - runs ok, shortly tested, win32 and linux Blaster Master (U).nes - runs ok, shortly tested, win32 and linux

and more explanation on a few:

Marble Madness (U).nes - required more accurate rendering, requires new renderer, not high priority. Kirby's Adventure.nes - requires fixed mmc3 irq, will be addressed soon Castlevania III - Dracula's Curse (U) [!].nes - mapper not supported

these are just off the top of my head, will post later about all issues.

testing against fceu isnt very good. use a more accurate nes emulator, such as nintendoulator.

the sound issues will be fixed soon. i did not write the sound emulator, i simply borrowed it from matt conte. i plan on writing my own or using blargg's apu. sound will be fixed, this project is just an infant.

thanks for the issue reports.

Willow (U).nes produces glitched graphics but Willow (U) [b1].nes runs OK. Blaster Master (U).nes cannot be loaded at all but Blaster Master (U) [b1].nes runs OK.

So what is difference between original (U) and all that [b1] [b2] [b3] [o1] [o2] and [o3]???? What that means???
