Love the artwork! Brilliant

Cool. Thanks for sharing :) There is an old trick for converting a binary digit to ascii hex that is fewer bytes than the branching version: adda #$90 daa adca #$40 daa Also, I wonder how the long multiplication compares with a version that uses 6809 MUL (8x8) to generate the partial products.

Doesn't RTI spit a dead cycle at the end though?! It does, but the beautiful thing is that it emits the stack pointer during that cycle rather than FFFF :ugeek: Something similar happens to allow say LDA ,X to work. It runs for four cycles: First two cycles are opcode and postbyte, then there is a ...

Not quite sure where this lies on the filthometer, but one code trick I'm fond of is using rts with a preloaded stack as a fast loop counter or sequencer. A similar thing can be done with puls regs,pc to quickly make a series of function calls with parameters. This approach is nicer because it respe...

Just some proof of concept code to access the rtc without switching roms.

Should help with getting one of these working in a Dragon 32.

That's some pretty tenacious coding you've pulled off there to access the rtc

The hi score table looks great, and I don't even need to add the qualifier 'for the Dragon'! It definitely captures the arcade feel

can you point me to the download link. i can't find it. sixxie only had time during his lunch break to push a source update, which I was able to build and can confirm it fixes my issue: So cheers @sixxie for that :) Also @sixxie Many thanks for the updated manual. Very nice. One thing with the buil...

Sorry for drip feeding you bits of info. I should have said I tried -machine-cart on the command line.

So in my case:

-machine-cart on the command line does not work with -run
machine-cart in .conf also does not work with -run on the command line
but
-cart on the command line *does* work with -run

I've just noticed that specifying both cart and binary on the command line doesn't work either. The loading of the cart is suppressed by the presence of the binary. The only workaround I've found is to put nothing on the command line and load the file from within xroar.
