Support for mapper 9

[actraiser30]

Hi,will there be support for Mapper 9 in a future release?

thanks

[Myself086]

No, this mapper is blacklisted. The note on the compatibility sheet says "Impossible to accurately emulate CHR bank switching".

Punch-Out won't be compatible unless someone wants to work with me on patching the game.

Any case that you can create a native nes emulator for snes instead of merging each time a game with the emulator? Thanks

Yes but it's very low priority on my list.

This emulator requires 4 files:

• The emulator program
• The NES game
• Save file for the NES game (sometimes)
• Save file for the emulator (feedback to exe)

But the SNES doesn't have a file system so SNES emulators and devices only provide 2 files:

• SNES program (ROM)
• Save data (SRAM) Which is why merging is necessary.

If someone wants to update firmwares for Super Everdrive and FXPak Pro then I'd be willing to provide all necessary information to make it possible. However, there's a new feature coming to v1.5 that would be difficult to port to those devices.

Did you ask to Krikzz and Ikari about ?

Maybe that guy here can help

https://github.com/hcs64/neon64v2

He made the native nes emulator for N64

[Myself086]

I know how to add support for mapper 9 but it can't be emulated perfectly on SNES due to the reason I posted above.

Games running on mappers 9 and 10 will need to be patched, will be tricky and isn't worth my time. I am not going to ask around for help on something that I know how to do. If someone wants to come in and help patch the game, I'd be open to that. But until then, mapper 9 is not happening.

N64 is powerful enough to emulate the PPU at a low level, SNES must emulate it at a high level.

Oh i see thanks,is there a list of supported games in titles?

Use this link or click the "Compatibility" button on the bottom left corner of the exe's main window.

Thanks Is it possible to add scanlines to the emulator by default or just as an option to select before merging a rom with the emulator ??

[Myself086]

I'm not sure what you're talking about.

[symbios24]

For the games to have scanlines that old Crt tv's had so the games wont show pixels,every emulator has this option at least for pc etc.

[Myself086]

This isn't necessary because the resolution on the SNES already matches that of the NES. The image would look very similar to a NES on a real CRT.

[symbios24]

I dont mean to add scanlines for crt's tvs i mean to add scanlines for tft's tvs that most people have and nes on this tvs look very bad since they dont have scanlines, .it can always be an option before merging the rom thought.

[Myself086]

It can't be an option because the resolution on SNES matches that of the NES. So it's impossible to add black lines between what would be NES lines.

Do you play to implement mappers from pirate games and unlicensed games? Because it would be cool to play those games such as gauntlett 1 & 2,pirated nes supermarioworld,donkeykong country “4” super donkeykong 1 & 2 among other pirated & unlicensed nes games on snes,

and in case you don’t wanna do that you can decide to make this project opensource sothat anybody can help completing this project as soon as possible😁

[Myself086]

NES Super Mario World absolutely yes, I made an editor for this game back in 2017.

For other mappers, it mostly depends on how compatible the mapper is to the SNES.

Any recent changes for a native nes emulator without the need of merging??

Thank you

I have no idea how to do it but if you find a way to implement it, feel free to let me know. Also, please keep issues on topic so I can easily browse through them later.

[symbios24]

It will be nice to find a way to do it like that since it will be not necessary anymore to merge hundreds or roms one by one. Unless you can add an option to merge multiple roms together.
