Rocco Corsi just announced this on the CoCo Discord: https://github.com/rcorsi/CoCo-xroar-variable-profiler It uses GDB connected to XRoar to profile BASIC variable use (to let you know which ones are worth DIMming at the head of your program). The breakpoint addresses are CoCo-specific, but could d...

Looking good!

Hmm doesn't seem to have helped on the high score screen. If it helps narrow it down, I noticed that 'M' is acting as backspace (which is where it would be in the CoCo matrix).

Is it the high score table on the real dragon that isn't working? which keys work/don't work? Just testing in xroar all upper and lower case letters work. I think I may have tried to be too clever and guess which type of keyboard is used based on the first few key pressing used, perhaps just checki...

Yep, the new version lets me enter my preferred keys. No joy on the high score table though.

Will do.

Meant to say I tried it on a real Dragon 64. 15120...

I didn't notice anything obviously wrong with the gameplay...

The keys that aren't recognised for configuration definitely include (1 9 A I Q Y CLEAR) (which share a column. or row, depending on how you look at it) and some others which you might be reserving including (UP C K S SEMICOLON).

I don't have convenient 32 set up to test on but it runs under emulation. Nice sounds and particle effects! There are a lot of keypresses it won't recognise though - while reconfiguring the controls and while entering your name. In CoCo emulation it was still picky about the controls, but I was able...

The only thing that comes to mind is that the iMMUnity needs you to use the on-board RAM for video - are you doing whatever it is you need to do to make video data go to the right place?

So Alan decided to pull the "no more GCC" lever for 6809 Fuzix, and after a while of him bashing against the fallout, the results seem to be pretty good. It sounds like the rapid 6809 development has settled down now, so seems like a good time to write this. It does mean all the 6809 platform-specif...
