Gateway to Apshai - Colecovision

I just learned that there is a Colecovision version of Gateway to Apshai. I had the ROM all the time, but never realized it.

Anyway, get this, it doesn't seem to have the Dungeon 7, Level 8 bug. It looks and plays exactly the same (except for the pixel aspect ratio) ... but it has completely different dungeons. In fact, it apparently has 99 different dungeons of 8 levels each instead of the usual 16x8. It still fits in a 16KB ROM. I didn't try all of the dungeons, but I did try first 20 or so and there no problems so far. I haven't really checked out the code yet, still looking for a decent Colecovision debugger.

The Colecovision version was written by Marc Ferguson and is copyright 1984 (a year after the C64 and Atari versions).

If the ROM is in the TOSEC, i must have it, but can you post it anyway?

I'm looking for a good recent emulator with debugger for this system too. In this case, i'll look to the seeds used and compare it with the atari ones. I think the dungeon building algorithm is the same.

Let's see if I can figure out how to upload Gateway to Apshai ... I can't figure it out. I'll PM you with a link.

As for emulators, I fooled with MEKA 0.71 a little. It can emulate Z80 consoles including the Colecovision. It has a debugger but I haven't used it yet.

Read the debugger.txt file for more information.

The thing I don't like about MEKA is that it can only run in full screen exclusive mode.

Ho yes, there's little bug in the upload mod (no text in the buttons).

I think you mean Dungeon 8, Level 7 :)

Right you are. I always meant to fix that, I guess it's too late now! :lol:
