I stumbled into the Intellivision programming forum and saw, http://atariage.com/forums/topic/275233-grail-of-the-gods-rogue-like-or-mini-rpg/. So I decided to take a look at his source code to add in graphics tileset for the level and the monster. I did the same for the PC version of Sword of Fargoal. Eventually I 3D rendered a grail and then pixeled it to fit the Intellivision colorstack specification. Then I decided, why not make a Colecovision port of the game? It exist on the Intellivision, Dark Basic, and TI99/4A. The source code are available.
The only thing I couldn't transfer over is the maze generation. It seems to requires number bigger than 8-bit in order to draw the maze. So, I got the idea from majestyx version to do a mappack. There's 29 different map, majority been taken from the level generated from the Intellivision version. There are some unique maps that have a treasure room guarded by a later level monster, a gauntlet which you fight through every enemy in the game, chess piece map, and etc. The item and monster are place randomly based on the rules provided. I added more adjectives to the weapon and armor in jest since they do break easily, just like Zelda:Breath of the Wild. I added animation and sound effects for the battle. I added easy mode to add 10 more HP, atk, and armor every level up. Easiest mode add 20 HP,atk,and armor.
Here's a youtube video: Gauntlet on depth 6.
I tried to restrict it to only show up after depth 6, but it got buggy that the case got taken and won't load the monsters and items that's not the gauntlet map. You might survive it at level 1:depth 1 who knows.
No music because I'm not brave enough to compose one.
And it is my birthday month and wanted to contribute something for the Colecovision, enjoy: GrailoftheGodbugfix2.rom
Edit:If you have the first 2 ROMS, it contains bug that lead to a black screen due to lack of wall for the objects. So GrailooftheGodbugfix2 is the fixed version. I deleted the first 2.
