Enabling 2P in any existing SEUCK game

earok · 27 September 2015, 00:52

I've been doing some playing around with SEUCK recently, although it's possible to edit any released SEUCK game in the editor it'd take a fair bit of fiddling around to add 2P support to games that didn't already have it.

What I discovered was all of the variables related to 1P seem to fall within this range in the ".all" file, bytes $17301 to $174DA

If you copy that range to $174DB, it seems to copy the Player 1 limitations, starting position, playfield and sprite animations across to Player 2. Though I'm a little bit paranoid that my range might not be correct, say it's entirely possible it might copy data unrelated to Player 1 to a different location.

If there's any interest I *may* look at making a rudimentary Windows or Amiga command line tool to automate the process.

Tested so far with:
- Raid
- Blood N Bullets
- Slap N Tickle
- Psychoblast

Well, firstly we should ensure if TCD is really a "great" friend.... Remember, we dont know why him is saying this.

[PS. I am only kidding, TCD is an excellent guy.]

Well, if you like I can add myself to your list of friends, good for you?

The only problem is cruising the Atlantic and the Pacific to play SEUCK games on the home of the other, WinUAE dont have Kaillera support yet.

So the only issue with enabling 2P option so far is finding someone to make use of 2P option?
