Yes, especially if they had to pay a huge license fee for the the prividge.

They're a little buggy. Not as good as mame on a pc.
-
Same gameplay better graphics. I'm assuming it must have had some kind of demo or prototype. As far as I know it's MIA.

Yeah, we need to wait and see until Infogrames comes for the Atari Age name and logo. Kind of like we waited and saw with the Nazis taking Poland (surely they won't....)
There used to be a pacman.com and a galaga.com. One morning everyone woke up and they both pointed to namco.com. It seems namco sued the owner for copyright infringement then dropped the charges when they signed over the domain names.

Maybe I'm not understanding you. On my multipacs I hook the reset on the 273 to the reset line of the cpu and then to a button. I didn't worry about it in this case since just toggling the power switch works.
This design is pretty much like mine. I had some occasional glitches in the banking and ended up changing mine to a write instead of a read.
IIRC I'm using similar addresses but only the lower half x00-x7f. Mine has 16 bits of registers to handle different bank switching schemes. I'm using a xilinx cpld for the logic. I have 2 ttl chips to try get the timing right on the banking and the ram chip.
Mine looks kind of like this one.

A friend of mine lives over in olathe/overland park. Until recently he had a maneater and a computer space both in his garage. The maneater was really cool, the cabinet was shaped like a shark with the monitor in his mouth.
The oldest machines near me would be the death race in the garage and the formula k and super breakout in the carport. And the oldest arcade game near me, Midway's sea rescue 1968 in my living room.

I don't need any credit. Due to excessive paranoia I'm not even using my real, fake board name. I try to use a diffent name in every forum or newsgroup I use.
Feel free to take any ideas you can from my work, and good luck with your project. I've always wanted to do a pc game but I'm too lazy to learn anything new, like PC graphics. The PC languages I do know are mostly console based or not very suitable for a game. -
Here it is. I think it was on my website at one time but I don't see it now. Run in mame as mspacmab or if you have a very old version it was called mspacman. Rename your current mspacmab or mspacman and name this file to it.
Use the coin button to coin up, then start. Start 1 fires 1 and start 2 fires the other cannon since pacman doesn't have any other buttons to use. The energy bars at the bottom show how many shots, so you have to alternate.
I doubt I will ever finish it. It wouldn't take much but I don't have any interest in programming pac hardware right now. Although when I do the colecovision project I may convert all my pac hardware games to colecovison that may encourage me to finish it.

I can tell you what happens in the arcade version. When they hit the wall they freakout and mostly just drift up, wrapping around the screen until the next level. Sometimes they do go staight ahead, but either way they''re usually hosed and won't chase you anymore. However it's not that big of a deal on the arcade version. If you put the dead ends on the edge they hardly every go into the tunnel due to the AI. Unless they're chasing you of course, but then it really doesn't matter. Xen's Revenge is probably the most popular version. http://www.xensei.com/users/jeffm/www/pacm...n/xens-revenge/

Is yours on PC? Mine runs on pacman hardware or in mame on PC, that pretty much guarantees an old school look. I never actually finished mine, it's playable, but iirc you can't be killed, or there's no timer.
-
Yes, you should be OK. Keep in mind that being in the right is not the same as not being sued. But I can't imagine anyone at midway/atari even really remembers the game and who has rights to it, much less has lawyers on retainer with nothing better to than hassle individuals. BTW this is what my version of space zap looks like. A rotating ball, I added a second gun. Any resemblance of the enemy ships to mt fuji is strictly a coincidence.
-
I"ve been trying to remember and I can't. Wasn't it atari that was throwing it's weight around with some of the smaller platforms. They'd threaten the small time author of a similar game and then since he couldn't defend himself he'd sign over his rights for nothing and they'd change the name back to Pacman and release it as is. Saved on porting costs.
I know I read that story somewhere, just can't remember where.
-
My lawyer tells me that you can't copyright game play, you can only patent it. And that's very unlikely. As long as you name it something different and make it look a little different you're probably ok. Of course that doesn't mean they can't hassle you.
-
Yes, Kev's very good and a good guy besides. I occasionally do repairs myself but I'm way backed up at the moment. I ususally do exchanges, 3 bad for 1 good, I'm all out of the goods until I get some time to work on them. All I have at the moment is bootlegs and the pins are different.
Be careful on an exchange if your board is really bad. Some of the big places(I won't mention any names) can decide your board is not worth exchanging and charge you extra.
-
I considered doing a ram cart for it. But iirc the way they did the write signal is not exactly trivial to implement. I had hard enough time making a ram cart that works half way decent with the "simple" system of using an address line for write.
-
Might I suggest a dremel?
You've got a dremel that plays imagic carts?
Sorry I couldn't resist.

GCC(they make printers now iirc) made Ms Pacman, they sold it to Midway MFG who released it. As they had a license for pacman they felt they were legally ok. The mspacman boards are a series of overlays onto the original pacman board in order to avoid any legal problems. As far as I know Namco never released a ms pacman. Namco did later force midway to give them the rights to it so they do own it now.
-
No, thanks to FPGA's consoles will live forever. Your pitfall 2 cart however is doomed.
-
have you played oil's well? It seems to be the same game as anteater.
-
I didn't realize you could use 2 driving controllers. I'll have to look into that. That would definately be worthwhile.

I haven't played death race since august of 1981 so I'm a little hazy on some of the details like attract mode. My memory may improve in the near future though.
I would guess the original attract mode the cars just drove around randomly, I can't imagine them using one of the prom chips to store input data for attract mode. I have a DR out in the garage but it's completely fried and I haven't had time to work on it yet. I have a spare monitor and some extra boards but I have no reason to assume they work either. -
..... I just wanna run over and kill people, is that so much to ask.
I know what you mean. My personal favorite is carmageddon 3 for the PC, although 2 is good as well. I loved the way the dogs yipped when you hit them. The strange thing is people(Mrs. Dav especially) get more upset about the dog than the people.
-
OK, I've got plenty of them. They come apart real easy too, I just opened one up with a razor blade.

I've got at least 1 thousand used eproms in stock. What are you looking for exactly?I'll have to look again because I dont have the prototype in front of me, but I believe it was a 4K 2732 EPROM by Mitsubishi.
Tempest
I have some of those. They have a raised square the width of the eprom where the window is and are labeled.
MSL2732k
8134OS

I was refering to the mentioned possibility of adding a line to the cpu.
It's probably because of the cpld but I was getting occasional spurious bank switches. I ended up making a seperate lock register, that required 7 bits to be written correctly before it would unlock. That helped but it still occasionaly unlocked and banked during the menu. That's when I changed it to a write, now if the data bits aren't correct I ignore any writes. This is the first project I did with cpld's and it was very annoying in that the timing is different, things just don't work the same.
There's actually 4 different registers of varing sizes up to 8. Origianlly 4xx was 1 register, 5xx another etc. When I changed to write I had to alter that slightly.
It's just a standard 2k ram. It works reasonably well for most people. I'd say around 80-90% The timing on the write line is a problem. Adding a buffer to the lowest 8 address bits helped a lot. But it really needs a much shorter pulse to work on every machine.
If I were to continue development I would probably work on that first. Also I've connected the required lines for 3f and pb banking, it just needs to be coded. I say "just" like it'd be easy, but I'm assuming there'd be timing problems there too.
BTW, I can do your boards for ~$6 but I'd have to order 50. If you just want a prototype I can probably work it into the next panel I'm doing for a reasonable cost. If you start adding features though you might want to look at cpld's, they aren't that much more.
