Moria - a dungeon crawler with 4500 rooms

Traveling down an internet rabbit hole led me to the Color Computer Archive and the VCC emulator.  As I have both a CoCo 1 and 3 in my attic, I have "dusted off" a couple of virtual disks containing software I wrote a few decades ago in case anyone finds them of interest.

Disk images:
Moria_CC1.dsk	For the 64K Coco 1/2
Moria_CC3.dsk	For the CoCo 3 respectively.

Files on the disks:  Note they are not interchangeable between versions.

START.BAS	Sets up memory for use and Runs Control.  Main entry point to the game.
INTRO.BAS	Same as Start, but doesn't run anything else.  Required before DNDMASTR (both versions), MON-GEN (CC3 only).
INSTR.BAS	Instructions.  Run From Control.
CONTROL.BAS	Main menu.  Run from Start. 
DND-GEN.BAS	Creates random dungeons.  Run from Control.
MORIA.BAS	The game itself.  Run from Control.
MOVE.BIN	Copies ROM to RAM.  CC1 version only
DNDMASTR.BAS	A simple dungeon editor that can also print out the floor plans.  It is not run from Control.
MON-GEN.BAS	Generates Monters data file.  CC3 version only
MONSTERS.DAT	Monstrers data file.  CC3 version only,
DUNGEON.DAT	Sample dungeon file.  Generated by DND-GEN.


This Basic game is a loose adaption of a mainframe version of a dungeon crawler.  Perhaps the primary interest may be the trick I used to cram a 4500 room dungeon into a machine with < 32k program space.  It copies ROM to RAM and takes advantage of the 8K "hole" above Disk basic. The CC3 version omits this (as unnecessary) and substitutes other actions.  It may have some improvements but it otherwise does not take advantage of the greater capabilities (e.g. still runs in 32 column mode).  I had started to off-load data structures to be read from high memory (i.e. monsters.dat) both to save program memory and to make things easier to change without editing the main program, but the one file is as far as I got.

I called it version V as a nod to it being more v.5 software.  It runs, but I did not balance the difficulty of play (e.g. mages start very weak and tend to die young, spells may not have the proper duration, etc).  It's all in Basic.  Change what you want.

Aside from the ROM/RAM swap and the high-speed poke, I don't remember what other peek/poke/ML routines I used.

For both CC1 and CC3 load the disk into the virtual drive 0 and run "START".

In VCC the Disk11.rom works for CC1 and hdblba.rom works for CC3.  I have not tested all possible rom combinations.
** Having the Keyboard set as a joystick disables the arrow keys and the game won't work! **

Moria_CC1 also works on MAME, Xroar (which actually simulates disabled video during the high speed poke), the JS Mocha online emulator and Jeff Vavasour's CoCo1 emulator.
