There's some build issues on Windows with QT5; I was able to hack around most of them but the big one is that QT for mingw doesn't support Qt's WebEngine at all. I replaced the QWebEngine use in the console with the QTextEdit from the original and it works! I am noticing some massive slowdowns when...

optiroc: does your branch still work on other platforms? (when building from source, no need for binaries) I'm interested in making some fixes/tweaks to the debugger; wondering to which repo I should send pull requests :) I haven’t tried in a good while, but I see no reason it shouldn’t compile wit...

I've merged these *awesome* additions, together with the latest changes from Revenenant and Undisbeliever, to my macOS branch. Pre-built binary here.

Have you tried to get in touch with ikari_01 about it? I’m sure he’d be happy to help with getting this addition to a releasable state. He’s usually around in #snesdev on IRCNet.

Except for the (damning!) fact that the VRAM data port register use word addressing, I see little reason to think about addresses in VRAM as word[n], when I think of any other address ever as byte[n].

I looked up information about the dec to hex converter, and it works by decreasing the 32-bit score by 100,000 and counting how many times it takes before being negative, then it does the same for each digit. Yeah this is a slow way of doing it. Not sure how to do 32-bit scores, but 16-bit scores c...

Stack relative addressing takes the same number of cycles as non-aligned DP addressing, IIRC – so that's a good alternative since then you also get fast access to scratchpad RAM. But for "heap object" access, DP-relative addressing is quite elegant. Also, stack relative access is rather st...

UPDATE: I just checked and it seems like these utilities already exist. :beer: I'll look into this more...not sure if there is a standard (i.e. most popular) one that most people use for patching SNES ROMs? Historically IPS was the dominant format and I'm sure there's still new translations/hacks r...

Great stuff! And challenge accepted!

Wow, I just skimmed through the documentation and have to say that there's certainly much to love about 64tass. I'll have to play around with it a bit for SNES use. Really, the only thing I like about ca65 is that there's as of yet nothing I could think of that its macro language can't accomplish – ...

Only for 6502, it says.

I should be more careful about posting two minutes after being forced out of bed...

I use the ".loword" directive to get the correct bytes into the vector tables, like so.

According to the manual ".addr" is an alias for ".word", so if true using it should yield the same overflow error.

One more useful feature that I forgot to mention: The ability to generate a symbol file for debugging purposes. ca65's linker (ld65) can output a pretty nice symbol file with the `-Ln` option. While trying to get various mapping types correct I've also found use for the `-m` and `-vm` options (expo...

I couldn't see it mentioned here so far, yet it's one of the most important things to realize for pixel artists targeting the SNES:

Pixel Aspect Ratio = 8:7
(for normal resolutions on NTSC display)

There's a YouTube series that sets out to visually explain most graphical features of the SNES: RetroGameMechEX. It's far from finished at the moment of writing, but here's a timestamped link to a section explaining how palettes work.
