The first 3 lines of my code.

; First attempt at real Colecovision Programing
; Adventure port from the Atari 2600 with due credit to Warren Robinet
; December 2, 2018 Start Date.

2 months, 5 versions and 4,000 lines of Assembly Code later I have a bug ridden 80%ish completed game then the lull once I learned that Quest For The Golden Chalice was already a game and it was 10x better than what I imagined to be a strait port.

The first idea was to make a completed Adventure clone as a Tribute to Warren Robinet thinking that Coleco came after the Atari 2600 it should be more powerful right? Jeese O Flip what a pain.

Also, after discovering TGC I had to make some major changes so instead of trying to trump TGC I decided to make it a Super Game expanded Adventure and this one will be mine and TGC will be theirs.

As far as the A2600 Adventure I looked at the source code and despite understanding it I am using a different system under Z80, Sound should be no problem but my first issue started with the colors.

Great on an emulator, sucks in real life.

Many people on Atari Age have helped me along in logic and understanding of the Coleco BIOS, Graphics and addressing memory. Without whom it would have been a rougher road.

Tony at Electric Adventures, Kiwi, Nanochess, NIAD, to name just a few. More to follow.

I know my first blog entry is jumbled but I got my thoughts out and I will start to flesh out the process and horror show of over engineering a simple game in order to make it work on a rival system.

and a couple of pictures of development and the rom since I took a break in February to work on my house.
