I have a small collection of crt files and wanted to use them with my
retro replay. Most of them can not be flashed to the rr without
modification, but as I'm a lazy person I didn't want to patch every
single crt. CRT8040 is a generic solution for one special cartridge
How does it work?
The crts I wanted to flash are mapped into the C64's mem starting at
$8000. Their length is $4000 bytes. Unfortunately the rr can just map
in $2000 bytes of rom at once, so the rest of the crt data will be
copied into the rr ram. A little reset routine will do this job.
It is implemented as a header which can prepended to the data section
of the crt file. Please take a look at the source for more details.
You will need DreamAss to assemble the source. Get it here.
The Makefiles heavily depend on Unix console tools like 'dd', they will
definitely not work with Windows. Please choose the binary distribution
for non-unix systems.
Copy the .crt's into the crts subdirectory of the source distribution.
Execute 'make' in the above directory.
The best place to give some feedback is the Retro Replay Mailinglist.
to get subscribed. If you own a Retro Replay this is a good idea anyway.
Please choose a private mail only for topics not suitable for the list.
