The MMC3 big CHR RAM test I was able to replicate that header with: .inesprg 4 .inesmap 4 .nes2chrram 9 So unless that's incorrect, looks like this is going somewhere. With regard to NES 2.0 mappers, there seems to be something of a difference between the assignments made by Kevin Horton and assign...

Are there any homebrew games (or even basic examples) out there that require use of the iNES 2.0 header? I've looked and have come up blank. It's kinda hard to try to implement 2.0 directives into an assembler when I can't find anything to test it with. (I'm willing to convert custom header insertio...

I might as well just upload my disaster here for anyone who wants to see. Running the fds gives a disk error. The code is very sloppy in that it uses previously made and bloated cfg files, gross looking code (not an insult to original creator but I haven't been going for cleanliness), and pretty sur...

I did try to make an old fds asm6 example compatible with ca65. It's...alright, I guess. A big problem is that the way I did things, files use a config called file.cfg and the final fds uses fds.cfg. For files, I'm just blindly assuming they'll all be size=$4000, and for the final fds I got lazy and...

I took a look at an asm6 fds example, and I don't think that ca65 is really the right tool for the job. You could use segments for the different files on the disk, but then you'd be modifying the cfg file constantly. Especially since the files don't seem to have a set size, and I don't think ld65 wi...

So would this tool just have to link a bunch of .bin files together and slap a header at the beginning?

A user wants to use an NES debugger on a 64-bit Linux PC but refuses to use any non-free software out of principle and refuses to install any 32-bit free software (such as FCEUX for Windows in Wine) out of fear that the 32-bit support libraries will take several gigabytes and "hav[ing] better ...

I'm in, if you want to go through with that.

I ran across this a few months ago, had to settle for an older version of the software. Maybe there is malware in the file. If there is, thanks to the magic of closed-source software, that was able to happen. If not, thanks to closed-source software, everyone lacked any reassurance or other ways of ...

My school restricted the schools access to NESdev for an unspecified reason, which I don't understand why, considering that this website is suprisingly educational! I don't know, I'd just thought I'd mention. NESDev has always been blocked at my school for "games". GitHub on the other han...

Just throwing this out there, asm6n's functionality has been added to freem's fork of asm6. The main difference is that it doesn't require INESINS or a flag to the command line. Turns out the assembler works differently than I initially thought a few months back. asm6n isn't updated with this improv...

Removing the parentheses fixed the problem, but I will consider ~~(using this) for other macros that may be mixed into formulas themselves.

Thanks all!

.define sprite(sprnum, sprattr) ($700+(sprnum*4)+sprattr) The above does its job, but it seems ca65 doesn't expect it to be a function when used like this: sta sprite(0, tile) (tile is defined as 1). Unexpected trailing garbage characters. The best workaround I've found is to add a "0+", ...

Ah, TASM! Sega 8-bit devs also used that before WLA came around. If there was a more modern assembler like that, I'd use it for pretty much everything. (Well, excluding the potential of ca65 or python to just have a macro pack full of assembler instructions ).

So the question's been asked about what tools commercial developers used, but how about the homebrew scene? What did people use before nesasm and friends came around, if anything?

I assume someone here knows since some of you guys are like, at least 200 years old. not meant to be rude
