VIC-20 MegaCart Support

@beamrider There's no chance there were two different regional releases of the cart, is there? Trying to work out whether it's a cart thing or a MiSTer thing.

Rally-X, that is included in the megacart, works. Could be that the cart is PAL only.

Many of the cartridge ROM images on mega-cart have been patched so they work in either NTSC *OR* PAL. mega-cart NTSC not working on MiSTer is either a core or "feature" issue as they definitely work on real hardware.

Thanks for confirming that! Hopefully that can be fixed.

Pretty sure, it's a single self-adapting cart.

Also, if you run up VICE, set the emulator to NTSC and attach the mega-cart ROM then Vic-Rally-X works without issues so it's definitely a MiSTer problem.

In the same vein id love to see the "PENULTIMATE+ CARTRIDGE" from TFW8B able to run on the Mister .. one thing I do miss using my Mister vs my real Vic20 ..

The mega-cart does everything the Penultimate does and more (apart from the TFW8B) games. A pity you can't really obtain them any more.

Yea but I thought the Pent did more now .. could be wrong but since the megacart is unobtanium its mostly moot I suppose.

I didn't even see the menu with the MiSTer core set to NTSC.

Looks like someone has filed a bug report about the NTSC issue, so hopefully it will be fixed in due course.

The core has a few timing issues with NTSC.

From todays update thread:

VIC20:

• Update CPU.
• Update VIC for better NTSC support.

Just gave it a try, at least the games I tried now run when launching the Megacart in NTSC.

Woohoo! Thanks for the update!
