Ok so for the record for any future readers this is a midway space invaders L shape PCB. I burned the deluxe roms and it would just nonstop reset as everyone said it would. I cut the trace to pin 10 of A3 and tied to ground. Game now booted and played fine except that pressing the 2 player start...

Oh, I am seeing on the schematics of SID A3 pin 10 and B3 pin 10 and 11 are tied to ground where on SI these pins are held high. Guess its time to burn roms and start trying stuff.

My preference would be to change the hardware and leave the roms intact. Not seeing port zero on the schematics but several other ports. Found reference in emulation that bit 5 on port zero is left direction? So not really sure what to be looking for in the schematics to ground.

I figured it would be something simple like this. Do you know what to change in the rom, or better yet how to mod the sound board?

I have a space invaders I want to run deluxe software on. I cant find any info on making deluxe run on original hardware just a few mentions that it wont work due to it looking for something different in the IO configuration or something. As this works with the multi I would assume there is a...

I dont think there is a fix out there for the intermissions, not that I have ever seen or heard of. But if there is these need to be combined into one fix.

I remember I wanted to do that. Honestly this was almost a decade ago, I don't remember most of what I was doing or how I was doing it.

This post was old but figured I would update I put this on romhacking recently where it should stick around for a while. https://www.romhacking.net/hacks/6758/

This is exactly what I had hope for as well, a good solution. Thanks for clarification. I support your reasons for locking but the fact that you had was not clear. Excited to see what you do with mk1.

I wish they had just come right out and said they were going to do a paywall instead of making it sound like they think you are too stupid to burn your own roms. And yeah it is a beta set with already talk of a beta 2, so if you pay them do you get updates forever? Just think they need to...

Its right on their download page. Nobody seems to be watching this thread so who knows what is up.

Was looking forward to checking this out but it says writing your own roms wont work and contact to purchase? Before I waste my time trying what makes it difficult to write 6 standard eproms?

Damn, missed your party 2 years in a row now. )-: I will hopefully not miss it next time.

Yes mame is a mess when it comes to primal rage. As far as I can tell though the mame Roms are clean dumps and not modded to get the game to run so on real hardware it should be fine. I don’t know where it pulls the serial from but it’s not in the roms. I am guessing it’s preprogrammed into...

I have what looks like 2.0 and changed out the 8 different roms that are in mame and it is now booting fine and displays 2.3 on the title screen. The thing I find odd is at the bottom of the screen at the title it shows "no serial" as the serial number. When it was 2.0 it showed a number...

Nevermind.

Ok cool. Thanks.

Nice, thank you. Does this have a polarity? Guessing positive to source?

My primal rage pcb is missing the left audio. It looks like someone had been trying to figure out the problem and reflowed a number of things by the amp. Did some testing and it looks like it is probably the c34 cap. Now my problem is what the hell is this cap so I can replace it. Does...

Finally got to doing an adaptor and reading this chip. I am sending to the author of the 4DO emulator now, hopefully we will see something fun come of that. If anyone wants this to convert a normal 3do to american laser 3do PM me your email and I will send it your way. Also pasted below is an...
