So I finally compiled the program I've been working on, and ran it in WabbitEmu (mac) and it immediately crashed. So following instructions I received on how to test, I created a breakpoint at $9D95 and ran the program. When the debugger popped up, I used Step Over (since the first instruction in my program is bcall(_ClrLCDFull). I would think that would step over the bcall, but instead I wind up at address $0caf. Stepping, stepping out, and stepping over now have no effect, and sometimes WabbitEmu itself will crash. What is so wrong with my program that a bcall will cause issues?

Could you post the assembled program and/or the source? And what version of wabbitemu are you using?

WabbitEmu says Version 2.1 (1)

This is the source that I compiled: http://pastebin.com/i2YRqWEE

... Huh? I'm pretty sure that the latest version of Wabbitemu is 1.9.5.20. That's the version on Codeplex, and checking for updates says that no update is available.

The Mac version shows "2.1 (1)"

Note: the 32-bit Windows version runs fine on Wine, and may be more updated than the Mac one.

I'm installing Wine as we speak and will give it a try. Will report back results.
