Jess Ragan Posted May 7, 2005 Share Posted May 7, 2005 Quite impressive. I'm not sure how it's going to SOUND when it's finished (this is a 7800 we're talking about), but right now it looks and feels very much like the arcade version. The collision detection seems a little picky to me, however. JR Quote Link to comment Share on other sites More sharing options...
uosipa llamxew Posted May 8, 2005 Share Posted May 8, 2005 I downloaded this when you first posted it, but I just now took the time to check it out. WOW! Now I really have to get a 7800! Already, this is the best Frogger port I have ever played! I'm using MESS (.87), so that very well may be the problem, but I have noticed that after some time the screen will go completely black and the frog turns yellow. The game contiunes, but I cannot see what happens until "splat" - I'm dead! I've had this happen 2 times so far; I was in a different spot each time and I can't think of anything that may have triggered it. @Kepone: Open MESSgui Find Consoles>Atari 7800 In the right panel, click on the "Device View" tab Click ".." and choose "MOUNT". Now browse to the directory of your 7800 ROMs. Double-click on the Frogger ROM. Click the "Picker" tab. The Frogger ROM should now be mounted and listed. Double-Click on Frogger and it should work provided your MESS configuration is correct and you have the 7800 Bios ROMs. Quote Link to comment Share on other sites More sharing options...

The collision detection seems a little picky to me, however. Yeah... the only things I would say at the moment I see are the collision detection being a little TOO close, and that compared to the arcade, the frog explodes on the square it was on, as opposed to where it actually went to (and where it got hit by something or missed a jump). (unless my memory of the arcade is shite, but I believe I'm right here) Quote Link to comment Share on other sites More sharing options...
Schmutzpuppe Posted May 8, 2005 Author Share Posted May 8, 2005 The collision detection seems a little picky to me, however. 851216[/snapback] Did you played the first or the second version I posted? In the newer version the collision detection should be better. I downloaded this when you first posted it, but I just now took the time to check it out. WOW! Now I really have to get a 7800!

Maybe it's really an emulator issue maybe not. Did anybody else had the same problem? Quote Link to comment Share on other sites More sharing options...

It's better in the second version, though still a little tight. You can be slightly away from the edge of the turtles and be ruled to die. So I saw. Apart from that, two thumbs up for what you've done so far I'll have to try it on a real 7800 and compare, as in MESS, playing it as PAL gets the screen all skewed.

For me it looks good on my PAL setup beside the fact that the picture is a bit lift up. I guess there are more NTSC users so I first want to make sure it runs on NTSC. Later PAL adjustmend is comparatively easy. btw. the colors are more PAL optimized (red instead of pink turtles ) Edited May 8, 2005 by Schmutzpuppe Quote Link to comment Share on other sites More sharing options...

Cousin Vinnie Posted May 11, 2005 Share Posted May 11, 2005 Damn guys, keep the 7800 development up. These new games look simply amazing. Qbert, Frogger, and Burgertime are three games I never cared about until now. Please release in cartridge form! Cousin Vinnie Quote Link to comment Share on other sites More sharing options...
oldbloke Posted May 11, 2005 Share Posted May 11, 2005 how does one make a cart for the 7800? i would guess it is similar to making a 2600 one. is there a document or website about how to do this? Quote Link to comment Share on other sites More sharing options...

However, I wouldn't be surprised if Joe Grand of Pixels Past and Albert have something on the drawing board. (Although a donor cart may still be required for the plastic housing.)

PacManPlus Posted May 14, 2005 Share Posted May 14, 2005 Regarding making a 7800 cart, I've heard of that solution before, but does anyone have a picture of where the chip gets soldered and what points? Thanks Quote Link to comment Share on other sites More sharing options...

PacManPlus Posted May 14, 2005 Share Posted May 14, 2005 Thanks Mitch! Ok so it looks like there's only 3 points that have to be soldered - cool. Quote Link to comment Share on other sites More sharing options...
Bruce Tomlin Posted May 14, 2005 Share Posted May 14, 2005 (edited) Ugh! I mean, geez, two of the pins are already in the right place if you flip the chip over! :-) This also works for 2600 Pac-Man boards, shifted two pins over. The cut trace is right under where the two wires meet. I usually put a small bit of electrical tape under the pins, but I removed it for the scan. (The extra wire is +5 to pin 1 so I can use the pair of Atmel 29C256's that I have.) EDIT: I've been thinking a bit, and I just realized that I could probably bend down three more pins (the inputs) on the "ground side" of the chip for physical stability. And likewise, two on the other side. It might not be worth the effort, but I can do it. Potting it down with glue or epoxy is still probably a better idea.

I have a schematic that I worked up in '00 for that cartridge if anyone is interested. Quote Link to comment Share on other sites More sharing options...
