Atariboy2600 Posted December 30, 2005 Share Posted December 30, 2005 For years I wanted some of the old 2600 "arcade-ported" games like Dig-Dug to be more like the arcade as closes as it can and I took time to try to see if the sprites from the 2600 can be as the real arcade looking and here's some sprited gif in motion and one pic from both the origranl and there updated looks next to each other Quote Link to comment Share on other sites More sharing options...

Atariboy2600 Posted January 1, 2006 Author Share Posted January 1, 2006 Right now Im doing the pumping and death gif for Dig Dug soon. Hope some one can do them on a real game^_^ Quote Link to comment Share on other sites More sharing options...
Feralstorm Posted January 1, 2006 Share Posted January 1, 2006 Oddly enough, I worked on some improved 2600 Dig Dug graphics too some time back. Mine were more working around the 2600 GFX designs than trying to closely copy the arcade graphics though. Quote Link to comment Share on other sites More sharing options...
djmips Posted January 1, 2006 Share Posted January 1, 2006 Creating a disassembly of carts greater than 4K is always a bit more challenging. Dig Dug is 16K and has 4 banks. What I do, with the current tools is to split the rom into four 4096 byte files. These files have to be changed from ORG to RORG. Then remove the START from each and then include each of them from a master file. Here is then is a quick disassembly that reassembles to an identical binary to digdug. digdug.zip TODO - identify areas of code that are in data (.byte statements) - find the location of the graphics in the data areas (for replacement) Note: Dig Dug is a Super Chip aka Sara game (ie 128 bytes of RAM mapped at $1000 - $10FF) Quote Link to comment Share on other sites More sharing options...
djmips Posted January 1, 2006 Share Posted January 1, 2006 p2.zip This is a replacement file for p2.s in the above source. I used the Stella debugger to advance lines until I was in the drawing code and found some of the graphics in the second bank. I re-disassembled using this config file in distella.

uosipa llamxew Posted January 12, 2006 Share Posted January 12, 2006 I dug (heh) through the ROM and found some locations for graphics. I'm not sure if I got everything, but I think it's close. There were some weird zigzags in the ROM too!

Nukey Shay Posted January 13, 2006 Share Posted January 13, 2006 I dug (heh) through the ROM and found some locations for graphics. I'm not sure if I got everything, but I think it's close. There were some weird zigzags in the ROM too! Maybe this is space that could be used for better graphics? Unlikely. More probable that it is a lookup table of bit values...which would be a zig-zag pattern if viewed as gfx. Hacking those would mess up the program in some respect...because the expected values would be all wrong. Quote Link to comment Share on other sites More sharing options...
uosipa llamxew Posted January 13, 2006 Share Posted January 13, 2006 I guess it just goes to show how little I know about the subject! I thought it was funny, because of the Dig Dug bootleg Zig Zag. Quote Link to comment Share on other sites More sharing options...
NE146 Posted January 13, 2006 Share Posted January 13, 2006 I guess it just goes to show how little I know about the subject! I thought it was funny, because of the Dig Dug bootleg Zig Zag. 999855[/snapback] Yknow what's funny is that thing aint ZigZag.. I mean it is, but the ZigZag bootleg that seemed to be super prevalant all over the place had a Pickaxe! (It made you go faster). Those pics on Klov look like just like regular Dig Dug with a different name in there whereas ZigZag was obviously different hardware. Anyway.. interesting Quote Link to comment Share on other sites More sharing options...
uosipa llamxew Posted January 14, 2006 Share Posted January 14, 2006 (edited) Interesting, I checked it out in MAME! the Galaxian hardware Zig Zag has some interesting differences including the pickaxe, while the Dig Dug hardware Zig Zag doesn't seem to have anything different besides the logo. The pickaxe is a nice feature... it's just too bad it isn't on the Dig Dug hardware bootleg because I don't really care for the glitchiness of the other. I've always been more of a Mr Do fan. All this time, in Dig Dug, I've usually killed the enemies with the pump instead of using the boulders. Until I opened up the VCS ROM and saw the bonus fruits, I'd never even seen any appear in the game! So I go back and realize that moving about and breaking the boulders (tilling the soil) made the ground more fertile and fruits and vegetable snacks were to be had! That realization alone just made the game 100 times more fun for me then it ever has been before!

Ringman Posted January 24, 2006 Share Posted January 24, 2006 I haven't looked at the code just yet but I could possibly give a Dig Dug arcade version a shot (graphics and color parts anyway.). Maybe I'll check it out later, its been a little while since I cracked open a binary for editing. Quote Link to comment Share on other sites More sharing options...
