remastering vorpal-newer g64s

Post by hyperactive »

Hello there.
I have a fluxed copy of California games. When I try to convert it to a g64, it works in the vice sps emulator, but it is impossible to remaster it with NibTools to run on real hardware, the game gets stuck as soon as it hits track 32.
Is there a solution to this? Is there a way to create a g64 that works on both emulator and real machines?
Thanks.

I''ve remastered it before, but you have to cheat and slow the drive motor down to 296 or so, and it takes several tries to get it right due to the write splice.

Hi.
Which version did you try remastering? the g64 that is created when you use the dtc.exe kryoflux commandline tool, or the g64 you patched for inclusion in the gamebase 64?
Thanks.

The track contents in g64 files created by DTC are not altered - and as such writing back them to do disk is not trivial, as vital mastering information is missing from the g64 format.

Well then I guess you just can't do it with a 1541. :)

Nice!

Actually what (the currently available) DTC does (in the case of generating G64 files only!) is that it generates a map of all the data found on a track which leaves it with choices for places where it could inject the extra bits needed for G64 as they are known NOT to contain any data, hence the operation is safe (at least safe for a few bits, certainly nothing more!).
It is also aware of specific requirements of certain formats, such as RapidLok and takes those into account.
