The wiki suggests that any write to an address >= $8000 will update the PRG ROM banks. However, the game
Wai Xing Zhan Shi 2.7z <Wai Xing Zhan Shi 2 (Ch) (Trad).nes>
will freeze after selecting New Game (the default option) from the menu after the title screen unless only addresses $8000, $8001, $8002 and $8003 are used. That is the only discernible difference I can find between emulators that can run it and those which do not.
Mapper 015 register address range

Re: Mapper 015 register address range
What other addresses does that game write to?
Re: Mapper 015 register address range
Just before it jams, it writes:lidnariq wrote:What other addresses does that game write to?
[$80FB] = $01
I wonder if that's some additional copy protection register.
Re: Mapper 015 register address range
Subor V1.0.7z <Subor V1.0 (R).nes> writes to $800X, $A00X, $C00X, $E00X, where X = 0, 1, 2 or 3. Consequentially, it doesn't run properly in emulators only using the addresses discussed above. The address can be masked with $8FFF; however, only a few modules of the subor application work with that change. It might expect banking logic beyond the standard mapper 015. It fails shortly after writing to $E001.
The .7z file contains an alternate version that uses mapper 166 and it appears to work. The .nes above fails to run if the header is adjusted to mapper 166.
GoodNES3.14 contains other versions of this subor application that do run better. And, interestingly, they include 2 flavors of BASIC. If anyone has the manuals for them, please post a link. I'd love to see what language features they support and run any available sample programs.

Re: Mapper 015 register address range
If it's mapper 15 and not 100-in-1, it's probably a hack intended for Nesticle or something, and will fail on accurate emulators.

Re: Mapper 015 register address range
The headers of the following GoodNES3.14 ROMs specify mapper 015 and they do appear to run in most emulators, except for the ones mentions earlier in this thread:Dwedit wrote:If it's mapper 15 and not 100-in-1, it's probably a hack intended for Nesticle or something, and will fail on accurate emulators.
