Mucking around on the Commodore 64 DTV

[rubber_jonnie]

No worries at all, just understand that I am ready willing and able to help with the project whenever you need me to :)

:2k2:

Thank you for your support.

You will be my first line of contact for any testing (or when something interesting happens). :)

Good stuff :)

As I was in a stalemate situation with other projects (see viewtopic.php?p=136881#p136881) I recently decided to have a fresh look at where I was with the C64DTV.

IMHO, theres not much that gives the same level of satisfaction as finding and fixing a 6 month old bug that has deadlocked a project. :D

And here we are...

I managed to fix the loading bug in the VICE DTV codebase:

viewtopic.php?p=127130#p127130

which with finding the correct VICE DTV drive settings - has unlocked the key to further progress.

Ive not got much further yet, but have managed to set up a file naming suffix system where a file can be split into 32Kb or less 'chunks' and the whole chunk set will be automatically loaded to DTV RAM.

So the C64 memory map is set up with a 32Kb window (hence the max. chunk size) and the loader will load each file in the split whole, up to the 2Mb DTV RAM limit automatically. :)

Whilst the screen blit size is incorrect (as you can definitely tell below) and I have not failsafed the routines (for things like rollover/overflow catching) and various other things (data stream continuous alignment checks and also it only works with my interrupt service routine for blit raster timing removed), it looks like Ive cracked the successful loading of >32Kb asset (64Kb in this case) to RAM/screen RAM:

Yeah, it looks crap and not not a massive progress update but Im exited. :lol:

:girldance:


More to come sooner now I can resume the work.
