It's in a forum that gets plenty of attention and maybe this will kickstart this thing to a newer and higher gear, it just takes one of us!!!

I'm still thinking on some programming issues. This is the first and only 2600 port I've ever done, so it's been a learning experience. In hindsight, I probably should have chosen a more popular game... It's indeed as MrFish says, most A8 users don't look here since there are less things going on here. I think you've done a great job with this conversion so far! Funny fact is that I never played the 2600 version a lot because I didn't understand what was really the point of the game. Now I've tested yours and finally know what to do, it's a great game! I hope you have enough motivation to finish the game! 1 Quote Link to comment https://forums.atariage.com/topic/319885-my-2600-8bit-game-port/page/2/#findComment-4952068 Share on other sites More sharing options...
Thelen Posted November 22, 2021 Share Posted November 22, 2021 (edited) And, may I ask if you've done the disassembly 2600 code yourself, or was there already a disassembled source with comments or something like that? I've never done a port, and I'm curious how the 2600 source looks... ?

glurk Posted November 22, 2021 Author Share Posted November 22, 2021 When I started on it, I just ripped the graphics from the 2600 ROM and created the display list / graphics from those. Matching it up with Altirra and Stella emulators. I planned to do the game code from scratch, but I then found Dennis Debro's commented source, (kudos to him) and figured out that I could use the original game code. It's a good thing, and it allowed me to get it done MUCH faster!! I don't think I'll be releasing my source code, because it wouldn't win any coding style awards, LOL. It's quite a mess... Of course, what matters is that the end result game is solid, and I believe it is. I mean, I like sausage, but I don't want to see how they make it, hahaha....

glurk Posted November 26, 2021 Author Share Posted November 26, 2021 Another question - for anyone. When I did this Barnstorming port, I pretty much chose all the color values "by hand." Because the 2600 palette is not the same as the GTIA one. But just for reference, is there (somewhere) a conversion chart?? 2600 Colors <-> GTIA Colors? I have one to convert GTIA NTSC to PAL, it's great. But no help with 2600...

sanny Posted November 26, 2021 Share Posted November 26, 2021 Probably you need two 2600<-->GTIA carts, one PAL, one NTSC. Quote Link to comment https://forums.atariage.com/topic/319885-my-2600-8bit-game-port/page/2/#findComment-4954618 Share on other sites More sharing options...
glurk Posted November 26, 2021 Author Share Posted November 26, 2021 I think my approach would be NTSC 2600 --> NTSC 8-Bit, and then use my existing one for NTSC 8-Bit --> PAL 8-Bit The 2600 and GTIA palettes are real close, but just not quite right. And it bugs me to death, LOL. I have to stop programming, open two browser windows, look up some online color charts, and compare. It's a huge time waste, one conversion chart would be SO MUCH EASIER.

glurk Posted December 1, 2021 Author Share Posted December 1, 2021 (edited) I've got the color thing sorted. More or less (to get close) take the 2600 values, and add 2, LOL. Not exact, but it gets close enough to hand-tune. But NOW I have a different problem. I'm working on ANOTHER port. A much more popular game, which I don't want to name yet. I don't want anyone to get excited about it, because I don't yet know if I can pull it off... Thing is, I'm not a graphic artist. And my vision sucks. So -- what I need help with... I have 3 8-bit wide "player" objects, and I need to expand them to 16-bit wide. Two bytes in width each. And I've given up trying to do it by hand. Is there some tool to do this? Can I do it mathematically? Maybe there's an easy way I'm missing. Maybe I'm just dumb... I guess a one-line example might do... .byte $85 = 'X....X.X' into .byte $C0,$33 = 'XX......','..XX..XX' Edited December 1, 2021 by glurk correction Quote Link to comment https://forums.atariage.com/topic/319885-my-2600-8bit-game-port/page/2/#findComment-4958101 Share on other sites More sharing options...

bfollett Posted December 9, 2021 Share Posted December 9, 2021 Just a minor observation: Looking at the original game and box art. There is a white fence across the bottom of the screen. Your fence is tan and appears offset by a pixel in the middle, so it looks more like railroad tracks than a fence. Not sure if it was on purpose but I thought I'd point it out in case it wasn't intentional.
