Commander X16

I was able to update my DEV0038 board to have the latest R45(prerelease) ROM, SMC, and also VERA FX.
Thanks for having these FX demos in ready for me to test easily.

Also, voidstar, I would prefer ZSMKIT now over ZSOUND. It supports much more capabilities.

Note these may require max memory. On the emulator, may need to do -ram 2048 in case it has defaulted to less than the max.

Small update.

I have separated the Mario Kart demo code into its own file and cleaned it up into something more readable here:

https://github.com/visual-trials/X16-Ha ... rio_kart.s

At the top of that file there are instructions to build and run it.

A few things of notice:

* the code started out as ROM code, but was later adapted to create a PRG (which can confuse a reader)
* originally the code did not use the KERNAL at all. This means it has its own i2c and keyboard logic implementation.
* for the loading of files from the SD card it now uses the KERNAL functions
* it still uses the vasm assembler (ca65 would be better, this can be changed if desired)
* it can be cleaned up further if desired

It can now be assembled with cl65. See instructions in mario_kart.s

Created a new repo:

https://github.com/visual-trials/SuperM ... /tree/main

It now runs on a X16 with 512kB.
