Re: Atari 2600 Miniature Golf

Any chance you would port the 2600 titles "Shooting Arcade" or "Sentinel" to the SNES for use with the SuperScope? That would be amazing. I don't know if you also work with anything from the Atari 7800 machine but "Alien Brigade" or the 7800 version of "Sentinel" would be awesome on the SNES using t...

Re: Hardware test program for Genesis Justifier, Menacer and\or ALG GAMEGUN?

Does anyone here know of a proper solution to replace the light sensor for the Justifier guns? I've been told it could very well be a custom part that is actually a phototransistor with a built in amp? I have tried many different phototransitors that have been suggested to me and I also built one am...

Oops! Well bad math on my part. That is way too much work then. I'm not pissing around trying to route that many address lines. The game isn't that interesting. :)

Re: 8k to 32k SNES VRAM schematic

Assuming, for the moment, that you mean "cart save RAM" when you wrote "VRAM" ... LoROM carts connect extra address lines in order, skipping A15. (So a 2KiB RAM is connected to A0 through A10; 8 KiB to A0-A12; 32 KiB to A0-A14; 128 KiB to A0-A14 and then A16 and A17) HiROM carts connect address lin...

8k to 32k SNES VRAM schematic

Hey All, Where would the extra address lines need to be routed to expand the VRAM from 8k to 32k? Would it be different on lorom VS hirom? The 8k footprint being 28pin is nice and a little easier for placement but I was also considering if a 2k could be replaced with a 32k as well? I have a 1a1m lor...

Re: Hardware test program for Genesis Justifier, Menacer and\or ALG GAMEGUN?

That's really weird. There's nothing obvious about the schematic that would make it obviously incompatible with both the Justifier and Menacer - there just aren't that many ways for a lightgun to work, given that the Genesis only supports "capture" on the TH pin. I was told that the LM311 leans to ...

Re: Hardware test program for Genesis Justifier, Menacer and\or ALG GAMEGUN?

I'm just gonna covert this to a player 2 "pink" justifier gun I think. Clearly after all this testing and research the American Laser Games GAMEGUN is not compatible with justifier or menacer games at all. I'm happy this is now at least "out there" to discredit the rumors and false claims that it co...

Re: Hardware test program for Genesis Justifier, Menacer and\or ALG GAMEGUN?

OK so now I'm finding out that ALG used a different hit detection method than Konami did for their gun games and hardware. Still I would think this homebrew test program should work as it's for all 3 kinds of lightguns but I'm still rolling snakeyes with this POS I have here..lol.. http://gendev.spr...

Re: Hardware test program for Genesis Justifier, Menacer and\or ALG GAMEGUN?

Here it is with all new through hole parts. Still nothing. I'm really at a loss. I wish I could find someone electronically inclined who also owned one of these guns. You guys have been great helping based on theory and what should work in practice and I thank you for it. The only thing that is orig...

Re: Hardware test program for Genesis Justifier, Menacer and\or ALG GAMEGUN?

Well this sucks. I replaced every last piece of population on this hunk of shit and it's still pretty grim. I even replaced the cord just in case. I'm hoping one of these smd's might have burned when I put them on, I highly doubt it, but that is why I bought an equal amount of through hole parts to ...

Re: Hardware test program for Genesis Justifier, Menacer and\or ALG GAMEGUN?

I ordered parts to replace everything on the pcb the other night. I'll replace the through hole components and the transistor first in hopes that does the trick. If not I'll start replacing those smd resistors and caps as needed. 2mm parts suck to work with...lol..

Re: Hardware test program for Genesis Justifier, Menacer and\or ALG GAMEGUN?

... I totally remember by trigonometric identities. radius/separation, not vice versa. Sigh. Anyway, atan(1.5cm÷2 / 10cm) = 4.3°. So is 4.3 degrees the viewing angle? You just jumped one step above my pay grade with the "atan". That is totally new to me and I know nothing about it aside from the fo...

Re: Hardware test program for Genesis Justifier, Menacer and\or ALG GAMEGUN?

You probably want to choose a half-width matched to the barrel of the lens then. What's the diameter of the far lens, and how far will the photosensor sit from it? There's no utility, and maybe some harm, in choosing a phototransistor that has a half-width larger than atan(separation/(lensradius/2)...
