It's awesome having 5 bosses, lol. In reality one of the main purposes of these "parties" is to teach people how to repair their games themselves so there's lots of watching and hopefully LEARNING going on.
Yes, I just got home from today’s (yesterday’s) event. We typically do them once or twice a month. We just posted pics from this event a couple of posts back. Fixed a Pole Position II with graphics issues, got a couple monitors repaired and brought a “Quasar” back to life.
If you open the info.mac file it describes what all these files are. They are not a “core” or anything related to FPGA code. Scanning through them quickly they look to be either original source files or disassembled object files for the original game. They include dumps of the ROMs and PROMs on...
Not all of them. Exidy's color games Star Fire and Fire One used a very unique method of separate memory spaces for the luma (intensity on or off) and chroma (color). The really interesting part is the color resolution was lower than the BW resolution so adjacent pixels had to be the same color...
Unfortunately the awesome AR2 design is not quite 100% efficient. Probably losing 20% or more in the transformer then another > 50% since the 5V is pass regulated from a 10.3V raw supply. This is not even counting rectifier losses wiring losses etc.
So you want me to believe this “customer” of yours had one of Scott’s Tempest multi FPGA kits plugged into his Omega Race cab with an “original spinner” and he “replaced” it with one of your Omega Race multi software emulation boards? Sounds reasonable. 🤣
Until you can get a good picture of PO/SPO that shows the detail of the individual red green and blue sub pixels will you begin to understand the difference you are “seeing”
There’s some camera focus issues going on here, perhaps related to the tinted glass changing the focal point of the camera or possibly the distance from the camera to the screen, was one of these pics cropped way more than the other? You can clearly see the RGB phosphor pixels in the left...
As much as I hate to validate anything ChatGPT comes up with, everything it came up with is accurate descriptions of why a video signal would look "sharper" vs "more smooth". Unfortunately most if not all if it doesn't apply to the Nintendo hardware nor the 20EZ monitor. It did miss one detail...
You're in Tempe? There's a local repair party happening this Sat. in Chandler, unfortunately I'll be out of town but @Arcadenut and @BigDogs will both be there. If you are using a Happ gun I'm assuming you are using one of my FPGA boards since the original gun works on 12V not 5V?
That was my first thought as well but I haven't seen any used in the arcade industry up to this point. There's not really anything needing that level of precision. I think it might've been some kind of inside joke between the engineers or possibly a "copy detection" scheme. Whatever it was/is...
