Ah with ndless. I thought there was a possible bug in the 3.1 OS that could cause this kind of behaviour.

PS: I have a completely unrelated idea: How about an "empy tns file" where you can paste your code and then it will forever execute the pasted code?

That's what oclua does (or at least the version I still have around) you write your script in a notepad or another thing, then copy/paste it in the lua script and it will execute your code.

A calculator that surprisingly only takes GB(A) games Just an idea, but how hard would it be to turn a GBA into a calculator? That way it may be something to try for those who have the means.

That update looks great, pretty impresive work you've done with this project. Maybe Alexis means a grayscale touchpad? I can see where that could cause problems.

Episode 5 has aired, hoping for some action

That sound make me think of something like a shortcircuit, I have no idea what could be wrong though. I hope it can be fixed

It works now, thanks So r0-r3 are literally scratch registers that just get arbitrary values throughout program execution?

I'm playing around a bit with keypresses and wanted to put something together with it. It's a very simple idea: detect a keypress, branch to the appropriate label, do your thing and branch back to the keypress detection loop. In my attempt below the ctrl key exits the program and the enter key branches to another part. My problem is that this branch stays, when it goes back to the keypress detection loop (at least I think it does), it keeps branching to the part where the enter key points to. Have I misunderstood something about ARM or am I doing something wrong codewise?
