I noticed exactly this earlier when I tried this game...........

It's been a very long time since I looked at source code but accelerating the cpu on the c64 architecture could be done whilst the cpu has access to the c64 bus.......

I would think this is how the u64 does this,

C64 control,,,,, run x mhz, vic control drop back too 1mhz.....

Just my 2p ........

I know exactly what you mean , when I got my casduino I found lots of games wouldn't work , I ran into 1 of those earlier with "pedro" which seems to not have a leader at all ( gonna have to try that on my real dragon) I ended up getting a new set from a site and they are the ones I use on the casduino which have worked quite well with th...

Yes exactly, again whilst loading into the dragon32, selected the file then did a cloadm, only happened twice in over a couple of hours.

Familiar tone-noise "found filename" tone-noise "loading data" didn't happen, after cloadm I just heard noise briefly ( no tone ) then error.

Tape (cas) support works very well with my cas files, some refused to work but I will have to try them on real hardware. Once or twice though I had to "stop / rewind" to get a cas to load though....... ( seemed to clip the leader ????? )

Tried the coco2 core today ( dragon32 ). Mostly works very well. Whatbi did struggle with was resetting the core, sometimes it would hang with garbage on the screen , other times it had inverted "@" all over the screen whilst other it reset normally. This also happened when switching between machines ( coco2/d32/d64 ) Would guess there's ...

Thanks for the explanation Ron. I have a little experience of fpgas so understand the differences in a linear program to concurrent fpga execution. It would have been more accurate too ask of the current state of the core , compatibility wise. I know the dragon had a funky clock stretching mechanism along with some really kludgy pal outputs. I will...

Very nice, Dragon was my 1st machine but always a cbm guy

What's compatibility like ??
