[FR] Suggestion: Game specific settings #92

Not an issue, just a suggestion, and I am so impressed with your project. It's amazing.

The64 allows the filename of the disk image, prg or whatever to have _ settings. While this is not exactly neat, it is EASY.

So if I have paradroid.prg, I could rename it to paradroid_j2.prg (for instance) with the _j2 telling bmc64 to set the joystick to port 2.

Joystick ports are certainly the most important thing I'd like to configure on the running of a game, but I guess also setting whether warp is enabled, ram settings, etc, would be useful.

Interesting. I can take a look at their conventions and maybe do something similar. Thanks for the suggestion.

Hi Rossi,

It makes the actual file name less pleasant, but I do think it's a very simple and effective way to inject settings.

Here's a link to where you can download their user manual: https://retrogames.biz/thec64/support/manuals-thec64

Taking a glance, it appears they support:

_J1 - set your registered controller to be joystick port 1 _J2 - set your registered controller to be joystick port 2 _M6 - set to 64 mode _MV - set to VIC 20 mode _TN - set to NTSC _TP - set to PAL _AD - accurate disk mode _RO - read only disk mode

They have a few others, but those appear to be the main ones

While supporting the filenname conventions of TheC64 would be pretty neat (if there were more ready-made collections floating around for the C64Mini but people seemed to have abandoned that), supporting the .CJM files might be even better.
