the advanced programming guide has a section on bankswitching... http://www.qotile.net/minidig/docs/2600_ad..._prog_guide.txt -paul

Very good. I definitely want to be finished with it before the end of the year. -paul

Hey, the game looks great!!!!! I agree about the ship. It feels too fast and there's too much friction (slows down too easily). In general the game feels too fast to me, but I'll need to play it more... -paul

Working on the battle kernel right now for H*R. It's a real pain, but I think it's going to turn out pretty cool. I'll post screenshots soon when I got something good to show. -paul

I'm not sure if this is any help (I didn't read the Stella thread on this subject), but I used a table to determines how the integeter X and Y velocity values affect the position for each of N number of frames. I believe it ends up with the same effect as fractional positioning. Takes up a little space for the table, but it makes the code extremely simple, especially if you include negetive velocities in the table. And you can easily tweak the speed of gameplay very precisely (which is especially helpful in PAL/NTSC conversion). I think I ended up adding a bit of a curve to Marble Craze table to get the gameplay just how I wanted it. ;4 frame velocity table ;frame1 2 3 4 byte 0,0,0,0 ; vel=0 | standing still byte 1,0,0,0 ; vel=1 | move 1 pixel per 4 frames byte 1,0,1,0 ; vel=2 | move 2 pixels per 4 frames byte 1,1,1,0 ; vel=3 | move 3 pixels per 4 frames byte 1,1,1,1 ; vel=4 etc. byte 2,1,1,1 ; vel=5 byte 2,1,2,1 ; vel=6

For Marble Craze I just used a velocity table instead of fractional positioning, so the math was trivial. I don't think the table needs to be very large either. Not sure if this would work for you, but MC has pretty much the same physics you need for hockey (including friction and bouncing off walls). -paul

He said it was just out on the curb somewhere nearby. I don't know much about arcade machines so I'm not sure. Although to switch from Robocop to Q-bert, the monitor would have to have been rotated. -paul

Personally, I think it makes more sense to post in the same thread. Why do we need two or more threads about the same thing? I got more offers for boxes than I needed, so I suggested that they might offer them to keilbaca. -paul

Yesterday my friend across the street found a Robocop arcade game on the street. He took it home and it came on, but there was just garbage on the screen, so he asked me over to look at it. I did the first thing I'd do on any old computer crap that doesn't work -- reseat all the chips and connectors. It came right up after that. The cabinet's a little beat up, there's no side art, and there's a faint Q-Bert burn in, but it's hard to beat a FREE Robocop machine. And the main board is plugged into a Jamma connector. That means we can plug almost any Jamma compatible board into it right? -paul

Thanks guys, I'm all set up now. Here's the info about my band and CD: http://treewave.com/cabana2.html -paul

I'll be putting my CD inside, shrinkwrapping them, and handing them out to select people as promos. Can't guarantee they'll be okay, but I expect that most of these people will think the boxes are really cool and keep them. Boxes for low-rarity games are not hard to find, and whenever I get games that are boxed and I don't want the boxes, I always make sure they get into the hands of people who do collect them. So I've done my share of box conservation. -paul

I need about 10 common early Atari brand game boxes, like Pac-Man, Defender, Combat, Space Invaders. Duplicates are fine. They don't have to be in perfect condition as long as they're sturdy. -paul

It's pretty common. I had one when I was a kid and I know a lot of other people who did too.

Looks awesome. Nice animation.

Did you try channel 3?

One time I got some games out of this guy's backyard. They'd been out there for a couple of months, and were in a container filled with rainwater. I dried them off, cleaned the connectors, and I think I managed to get all of them working. -paul

I seem to remember reading somewhere saying that they DO still receive screenshots fairly often, and to please not send them anymore as there are no patches left. I was going to send in a picture myself until I read that. -paul

I just tried an Atariage copy on my 7800 and it works fine. -paul

If it has the Hozer Video logo on it, it's an early release. If you got it from Atariage it's not. I've tested it on a couple of 7800s, but different 7800 models vary in how compatible they are with 2600 games. There's more about this in the 7800 FAQ: http://www.atariage.com/7800/faq/index.htm...l?SystemID=7800 Do you have a 2600 you can test it on? -paul

I'd like to see one of the newpaper articles about it. Particularly one of the ones from New Mexico. A trip to the public library should settle this... -paul

Yeah, the game's going to be delayed a few months. I've been too busy with my band and some other projects. I am continuing work on it and I'll definitely be posting new screenshots and possibly a new demo in July. -paul

I used to go to my dad's work and use a laser to see through the pieces and know which one's to scratch off to win. -paul

I took a quick look at the ROM and I quickly found the clues, however they are in the wrong order and the last clue is replaced with a different one. It appears they anticipated people trying to hack the ROM! Also, this data is in the upper bank which would be tricky to access. Here's what I found in the ROM: 01 0a 02 01 0b 01 03 01 0a 02 02 06 08 05 03 0a 07 07 05 05 07 01 04 04 06 03 0c 03 05 04 03 02 01 These correspond to the clues, but two are out of order and the last one 21-1 is not a real clue according to the solution. The real last clue is 47-5 which isn't present here. The fake 21-1 points to this page in the comic, where I guess the prominent word is "revenge"? http://www.atariage.com/comics/comic_page....&CurrentPage=23 Here's the solution page: http://www.yosemite-sam.net/Solutions/Swor...quest/Earth.htm

I'm convinced the person who figured out Earthworld dumped and disassembled the ROM. There were a LOT of people who knew 6502 assembly at that time. Has anyone ever tried this? I'm curious how difficult it would be to find the solution this way. -paul
