You guys know there is a way to DMA 1bpp tiles without having the CPU manually convert tiles, right?
I do this in my current project for 1bpp BG3 and 2bpp sprites.

Re: Project Nested - NES emulator for SNES

Soon after you released this tool, some smart merchants used your works to pack NES ROM and sell them as SNES multi-carts. Some of them crashed due to imperfect emulation. I wonder if the manufacturer of this kind of cartridge has contacted you? If we are using open source products to do business, ...

Re: Project Nested - NES emulator for SNES

Hey, I sent you a second PM, I don't think you saw it? You didn't reply. I'm new to forums, not sure how they work. Just basic compatibility reports not yet listed, nothing much, feel free not to reply, just trying to help. Found a whole game that works without any problems, thought you'd like it. ...

We need to create a pack with patched working roms!

Unsure on the legality of this, will gladly delete.
Not legal.

You are allowed to share profiles generated by the EXE. They only contain descriptions of the ROM file without actual data.

Re: Project Nested - NES emulator for SNES

Hello there. I haven't been on this site for a while, but this is a good emulator, I just want to know if the NES game is normal or changed and where does the ROM start, $10000, $8000, or $4000. Short answer: NES ROM data starts at file address $040000. The NES ROM data itself isn't changed but NES...

Re: Project Nested - NES emulator for SNES

is it possible to have the compiler automatically load in the settings for the games that require them before the .smc file is built? Yes, I eventually want to have a database that the exe loads from so settings and known calls are loaded immediately. Having a list of known calls boosts performance...

Re: Project Nested - NES emulator for SNES

Are you updating the compatibility list on your own? I've tested several games and found one or two that worked and aren't on the list, i would be happy to help if you want. I contributed 15 or so entries on the compatibility list, everything else is Memblers. If you want to add some game notes, yo...

Re: Project Nested - NES emulator for SNES

Update is out! With the number of games that were tested on v1.0, I decided to hold the update for a bit longer until I get the blue screen ready and a few other things. I've been very busy after my last post. My next focus is to spend more time understanding Github and start uploading experimental ...

Re: SMB Title does not render on title screen

In my experience, the palette for score was wrong until I added reading $2007 so you're doing at least something correctly. Is mReadBuffer only used for $2007? I'm guessing something else is rewriting it when it shouldn't. The cached read value from $2007 should only be modified by reading $2007 (as...

Re: Project Nested - NES emulator for SNES

I added a blue screen when an exception is thrown. The emulator was designed to trap the CPU with any 8-bit branch pointing to itself which was mainly used to be detected by my private SNES emulator. I finally got around to associating an error message to almost every one of them and showing it on s...

Re: Project Nested - NES emulator for SNES

Once it is in a stable state, I wonder the possibilities romhacking these games would be like if the NES emulator supports the SNES capabilities. Now even the NES games may even have MSU-1 capabilities. :D Reading controller input has access to all 12 SNES buttons as of the current release. There's...

Re: Project Nested - NES emulator for SNES

In the compatibility document, for Crystalis, it says "Requires patch for idle loops". How might I go about enabling that patch? The patch was made in collaboration with Steve_Hacks and can be found here: https://github.com/crystalis-randomizer/crystalis-randomizer/tree/snes/patches Download snes.i...

Btw, I posted a video of this project at work on YouTube... at least on a Super NT.

Awesome! Thanks for uploading! :D

The screen transition full of zeros in Zelda never happened in the pre-release version, I'll have to investigate.

As for Mesen-S, $43xB is open bus but it should be fully read/write-able
Do you mean that Mesen-S treats it as open bus? Because 'fully read/write-able' implies that it's not open bus.
Mesen-S treats it as open bus but the real hardware has unused DMA memory there.

Sorry for the poor wording.

Re: Project Nested - NES emulator for SNES

Thwaite seems to sprites issues and crashes shortly into the menus. BG looks fine though. Sprite issues are from writing $88 to $4014 (only supports $00-$07 at the moment). That could be an actual bug. It shouldn't be writing any value other than $02. What is the other code around the write to $401...
