Re: Need guidance with nes to snes.

- Sprite pattern table can't be swapped since the second table is a limited offset from the first. Doesn't it wrap? The address formula given here does & 0x7fff to the result, which implies that it does. Max offset is 24 KB (or 32 if you include the size of table 0), so you should be able to put ta...

Re: Need guidance with nes to snes.

I am working on a NES emulator for SNES. Here are some additional notes for you: - Sprite size 8x16 is not found on the SNES and has to be 2x 8x8. SNES supports 128 sprites on screen instead of 64 so it isn't a major problem. - Sprite pattern table can't be swapped since the second table is a limite...

Re: Question about resolution and sprite placement?

I'm guessing for the x and y instructions, you start from 0 in hexadecimal, then go further up, equal to the desired pixel location on the resolution. So for example, lets say I want to place the sprite at 142x182, I would enter $8E and $B6. Is this correct? You don't need to write number in hexade...

Re: My Nes emulator causes the main character's body in Kung Fu to split in half?

0x3000-0x3eff is a mirror of 0x2000-0x2eff does that mean data written to 0x3000 - 0x3eff is also written to 0x2000-0x2eff? Yes and I didn't know about this mirror, thanks. My NES emulator doesn't support it. Data at this range isn't "also" written to the other range, mirrors work by masking part o...

Re: Project Nested - NES emulator for SNES

I can start one if you want, just need to know how you think should be organized, like a CSV file, a SQL database, a server with files for each game, what do you think? As of now, the exe loads the profile with the most amount of starting characters to the NES file. Let's take Final Fantasy Randomi...

Re: Project Nested - NES emulator for SNES

Hey Myself086, do you think that compilating a document with the crash errors of each game and details of configuration would help you? At least of the ones that crashes to Blue Screen? The spreadsheet already has that. It has just enough information to give me some clues as to what might have gone...

Re: Project Nested - NES emulator for SNES

How about fixing these bugs I discovered: Thanks for letting me know which games you want to see on this emulator. Please be patient as this project is at least 10x more difficult than making a NES emulator for PC. Ufouria, Kirby's Adventure and Bomberman were already games that I want to emulate. ...

Re: Project Nested - NES emulator for SNES

Update is out! Not a major update in terms of compatibility. Some performance improvement but nothing too major as there isn't much time to save. Indirect JMP nearly halved its overhead timing by avoiding the use of X/Y registers but at the cost of an entire bank dedicated to code that previously re...

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. ...

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...
