New openbor games on dreamcast

Post#1 » Mon Jan 01, 2018 9:42 am

Hi, due the fack that the dc openbor engine is outdated and still need a lot of optimizations, the most part of the new openbor games don’t run on dreamcast.
So I decided myself modify some openbor games
to play on dreamcast.
Some of they was easy to convert and get to work,( I took less than an hour) but another was not and took lot of days or until weeks.

They are:

Doom Ultraviolence
http://www.theisozone.com/downloads/dre ... lence-bor/
Changes:
Converted all chars and bgs images to an global 8-bit pallete to get speed it was too slow in 16-bit mode,
Fixed an fatal error in the first level which was freezing the game.

Teenage Mutant Ninja Turtles & Battletoads
http://www.theisozone.com/downloads/dre ... ttletoads/
Changes:
Converted all chars and bgs images to an global 8-bit pallete
Edited levels txt and models.txt to free RAM Mem
Disabled 3 playable characteres to free RAM mem.
I had to split the game in 5 chapters

Contra Locked and Loaded
http://www.theisozone.com/downloads/dre ... oaded-v20/
Changes:
Converted all chars and bgs images to an global 6-bit pallete to get speed and free RAM,
Edited levels txt and models.txt to free RAM mem,
Disabled 3 playable characteres to free RAM,
Edited some levels.txt, and some chars to free RAM,
I had to split the game in various chapters because the engine get out of memory and reboot while load more and more levels, the engine should clean up memory but it don’t do it.
And other small changes that I cant remember.

Saint Seiya
