Commander X16

I thought of this while driving home, and had it half written in my head by the time I actually got home.

A 4x4 memory matching game! Simple rules. Use keyboard or gamepad. Can take turns using any gamepad 1-4, end game will show number of guesses and elapsed seconds for the round. There is also different audio when making matches or failing to make a match.

Uses PETSCII symbols. Surprised it hasn't been done before (as far as I'm aware). There is a bit of interesting logic to randomly pick symbols and ensure a random arrangement of pairs of symbols (and no repeats, so each pair is unique for that round).

WARNING: This makes use of the TDATA keyword, so this requires the actual Roswell R47 ROM (not the R47+ pre-release that many systems were shipped with). You can update the System ROM using the older updater in EXPLORE/SYSTEM/ROMFLASH-OLD/FLASH-CX16.PRG (SMC and VERA update is not required at same time, just copy the R47 Release ROM into ROM.BIN in that same folder).

"Super Memory Match", an expanded version that is now 8x5 (40 cards) instead of 4x4 (16 cards). Also adds mouse support.

Keeping the original post for the 4x4 version in case folks prefer that (as kind of a short-play vs long-play options).

EDIT: Corrected a small bug in the symbol selection (I put in a wider range of symbols, but one of them ended up being SPACE- if that got selected, the card became "un-selectable").

This is great. I always love a good memory game (even if I have the memory of a goldfish!). Thanks for this!
