Homebrew blargSnes -- SNES emulator for the 3DS (WIP)

[the_randomizer]

Version 0.218 seems to be the version with a working memory viewer, 0.230 beta 6 the memory viewer is broken, so avoid that. But given the history, the emulator is pretty damn accurate. So yeah, use 0.218 English if you so choose

This is the emulator I liked the most Plays my smw roms hacks perfectly

Incidentally, I found the absolute, bleeding edge version, 0.230 beta 7 http://gigo.retrogames.com/bbs/file/snesgt0230b7e.zip The memory viewers work properly this time.

Still from 2011, but the most up to date I could find navigating their Japanese site.

Oh right, this is the version I have, found at emucr. I should have linked it here.

For some reason, SnesGT doesn't like Windows 7, won't let me apply a basic filter (linear), huh...oh well

 

[DingoDango]

why did you name it blarg?

Perhaps he should have called it BlarggSnes?

Use compatibility mode, that should work.

Nada, not working, those pixels look horrible on a 1080p screen. Any filters I can download? Using beta 7, all I see are four options, but nothing filters it.

Judge Dredd crashes right after I get past the beginning sequence after starting the game. It just takes me right to the home menu and my 3DS asks me to restart.

Hi. I'd like to adress the subject of nightly-builds again.
I know, I know, StapleButter doesn't want his official thread flooded with links to unstable incremental builds, so that people don't ask support for them. But! Considering I really have no idea how to build them from GitHub sources, I'd very much still appreciate to be able to find the latest unsupported versions somewhere, just to try out the latest improvements.
For example, I've seen that StapleButter has added stereo sound to blarg last night, and I'm dying to check it for myself. I know what some of you will think: "compile or wait, you fool". Still, wouldn't it be nice?

It isn't that hard to set up a development environment. http://3dbrew.org/wiki/Setting_up_Development_Environment

The tricky part is that
you will need a slightly outdated version of aemstro though because of recent changes... (I could give you a commit checksum or even a zip file but I'm　mobile)

Consider it a trial by fire, it'll make you stronger.

I'm using this older commit version:
https://github.com/smealum/aemstro/commit/59828591e8adc7501ea401877458e9994f7b649d

Some games don't have compatibility with it, some do, and I haven't checked whether its this version. The ctrulib from github is also constantly being updated, so using a different commit from that will also probaby yield different compatibility results. One of the reasons why I don't think reporting issues with games using your own compiled version of blagSnes actually helps is, folks aren't reporting in which version of aemstro or ctrulib was used when compiling it. Also we don't know which version of these that StapleButter is using when coding and that again is another variable that isn't known when reporting bugs.

I can provide a good aemstro but I'm still having ttrouble compiling this one homebrew :\

Have an rsf, everything setup etc... can compile other brews fine. BUT,I get a 64 bit not compiled in error on makerom
Anybody? I'd love a more recent .cia build.

Using a different version of aemstro or ctrulib probably won't change compatibility much. Most likely, if there's an issue with how a more recent/old commit of either implements something, it'll fail spectacularly with everything.

In the meantime, I think I know what's going on with Home Alone. The game is merely saving one byte of space by exploiting open-bus behavior to run a no-op function.

When it jumps to 0x60AB, the last byte of data read is the MSB of that address, 0x60. The address is mapped to nothing, so it's open-bus. Thus the CPU, after jumping there, reads 0x60 as an opcode. 0x60 is RTS.

blargSNES doesn't support that. If my theory is true, that should make the game playable.

I also need to do more proper open-bus emulation. Most of the places just return the MSB of the address being read, but this may return a wrong result if indirect addressing is used (a read from 0x5000+X with X=0x0200 would return 0x52 instead of 0x50 for example).


Edit-

Well yeah, my theory was right.

The weird jump to 0x60AB was intended behavior. Hah, the tricks programmers pulled back then...

 

[hippy dave]

Yeah assembly language programming was a very different beast. Great work figuring it out

 

[Arisotura]

But it's still odd nethertheless, if they really wanted to save space they could as well have salvaged a RTS instruction from anywhere else in their code.

This is probably an attempt at thwarting copiers or emulators of the time. But who knows

 

[DSoryu]

I wanna test this so bad once I get my Cubic Ninja copy

 

[davhuit]

Super Punch-Out crash the emulator after the "Nintendo" logo (and the sound of the logo have some crackles). Can't click on the bottom screen to change the game.

I'll retry it once 1.3 is released though, to see if it's fixed with all the last changes.

True, it does fail pretty spectacularly, at least the last three commits. Current Commit won't compile, the previous two compiled and the lower screen ran but the upper screen just flickered rapidly and displayed nothing.
