For playing CoCo 1&2 PMODE3 games on a CoCo3 with enhanced color and higher clock speed

DOWNLOAD:  GAMEMENU.ZIP



This is a simple BASIC program I wrote to select and load some of my favorite PMODE3 CoCo 1&2 games for play on my CoCo3 and enhancing the 4 colors used by replacing them with colors chosen from the CoCo3's 64 color palette.

It does not modify the game but merely redefines the color palette slots of the CoCo3 BEFORE the game is executed.

Note that the border color of Green or White cannot be changed for the PMODE3 graphics modes.


I also added a selection for choosing to play these games in the higher 1.79MHZ speed of the CoCo3. Some games may be too fast to play while others can benefit from the speed boost.

To finalise the program, I also allowed support for people with a Composite NTSC monitor and the program will convert the RGB chosen colors to reasonably accurate CMP colors. This conversion is based on Erik Gavriluk's conversion calculations which he used in MAME.

Many thanks to L. Curtis Boyle for spending time with me to work out the best (to our tastes) color choices for each game.

Games were located off Guillaume Major's CoCo Software Archive:    http://www.colorcomputerarchive.com/



ADDING GAMES AND CUSTOMISING COLORS

To add games to the menu and configure your preferred color selections, you can EDIT or insert DATA lines into the BASIC program.  The last DATA line must have an "*" to indicate the end of the list. A maximum of 9 game entries can be displayed on the screen.

T
hese lines are at the beginning of the program listing. Each line contains the <FULL NAME> of the game, followed by the <FILENAME> used to load the game (.BIN is assumed) then the 4 x <RGB> values of the new colors. If Composite Color is chosen, the RGB values are substituted during run time by the program.

Blue sky and green mountains on the moon?!!   Change those colors and make the moon great again!

Magenta (pink!) sky and cyan tree?!!  What were the programmers smoking?!

Not too bad but we can reduce the excessive "nuclear green" by using a darker green for the grass.



Phantom Slayer
Standard PMODE3 colors

A bit too bright and cheerful for a scary game. Added some mood by reducing the colors.


COLOR OPTION FOR THE CoCoVGA

This program could be tailored to also work with the CoCoVGA running on a CoCo 1&2. The CoCoVGA will allow you to choose colors from a 512 color palette. You will still be restricted to only 4 colors because this is all the PMODE3 mode allows.

The high speed clock option needs to be ignored for now until a double clock option is provided for the CoCoVGA.


Happy CoCo'ing!
