The closest we'll get to Pac-Man Plus on the 2600...


PacManPlus

Recommended Posts

I did a hack of the graphics/colors to see how close we can come to Pac-Man Plus on the 2600. ;)

Now the only things it's missing are:

1) Turning the ghosts blue by eating the fruit (and scoring double points when you eat them)

2) Making the maze/dots disappear somtimes when you eat an energizer

3) Sometimes making one of the monsters not turn blue when you eat an energizer, and

4) Speeding up the whole thing

 

Can anyone help?

 

P.S. - sorry for the bad conversion of the graphics - I'm no artist!

 

enjoy!

Thank you - and Welcome to AtariAge!!!! :)

 

I've been wondering how hard it would be to just call the subroutine to turn the monsters blue once the fruit is eaten (assuming it's a subroutine)

 

Also, I would need a random function to make the maze color transparent when an energizer is eaten... Unless I am missing something, I don't think it would be that hard. I just have to try and figure out the disassembly of Ms.PacMan. I have 'raindog' to thank for documenting some of the code for it.

 

Anyway, thanks for the reply :)

@Breakpack: In PacManPlus (the arcade version), the monster's eyes are one pixel closer together when looking left or right, and they are one pixel lower when looking up (I wonder why?) I'll have to check your version out to see what you did :)

 

Here are some screen shots... One of the blue monsters, and one of the 'Pancake' Level:

Thanks Sku_u :)

 

BTW I saw the post in the 2600 thread about the WIP of PacManPlus - that was very nice of you Breakpack :) I am still working on trying to figure this stuff out by myself, I have disassembled the rom (thanks to Distella, and breaking the program into 2 - 4K parts), and have mapped out the graphics section of it. I might need a little help trying to figure out where certain routines are, so any help is appreciated :) I have included how far I got here (not the binary, looking at the source) - NOTE that I started with MsPacMan, not the hack.

 

Regarding the colors, Rob Kudla has documented where the colors are in the file - just download his binary, and look for the .txt file in there - it explains everything.

Nono...the text file in the zip (from the link, not the attachment) has descriptions of what was changed when creating A Better PacMan. For example, the SHOWGFX locations for the playfield color table is at 1d16, ghost colors are at 0b82, etc. The zipfile is here:
