Re: Macros that define visible labels in ca65 and ASM6
Just tested here, but if you define the symbols you wish to use in the macro before the macro is run, changes made to that symbol with = will apply to the outside definition of that symbol, rather than being locals. According to the ASM6 readme documentation symbols created with '=' can be reused. a...

Re: PC Engine dev - Memory Base 128?
Oh, thank you for sharing that! :D That thread gives enough idea of how to read/write to the MB128 through the joypad port, which is excellent. It seems the filesystem structure is still unknown, aside from the initial header after formatting. Still, you could probably just decide on your own format...

PC Engine dev - Memory Base 128?
Hmm, recently I discovered the Memory Base 128 , an underutilized external memory device for the PC Engine / TurboGrafx-16. I know that it's a memory device that attaches through the controller port, which can hold up to 128 KB of save memory powered by AA batteries. This is ideal because it connect...

Re: em-fceux - FCEUX for the web
This is very cool! I had actually discovered this earlier today while trying to see if someone had already made an emscripten port of FCEUX, and lo and behold, somebody did! If it's not too hard to get going, I'd be interested in contributing / making a fork with the following features: - more class...

Re: Can Everdrive-GB run homebrew?
If you need to reset the Game Boy CPU of the Super Game Boy from software, it should be possible. You could run code uploaded to the SNES RAM via SGB commands: DATA_TRN / DATA_SND ( DATA_SND is more efficient for small transfers, since you don't need to setup VRAM to send the message, you just use t...

Alrighty, there have been a few updates to nel, as of late that will make it a little bit easier to use (hopefully). Recently started working on it again because a person that I know from online was recently trying to compile nel's compiler source in the most recent version of D2 (There were a few d...

I am too lazy to read the manual at the moment (the non-assembly codes hurt my brain already but people unfamiliar with assembly may find this easier to handle) and I tried to assemble the test rom but failed, with some garbage error message: http://i488.photobucket.com/albums/rr249/gilbot/nel_erro...

nel - Another 6502 compiler for the NES.
Hey there, my name's Overkill. I've been lurking NESdev for a bit, hanging out on the IRC, and making a homebrew project. I think a few people on #nesdev may have heard about my assembler sideproject already, but I've recently made enough progress on it that I think it's probably okay to release. On...
