It will take me a while to get back into this issue you are having as it's been a long time. So some questions: Are you certain you board works fully with a standard cart? The videos you posted have rolling frame, is this just your monitor? You need to post a good picture of your cart so I can...

Your best bet is to read in your 8b, 8c, 8d roms are let the patcher detect which version you have.

Here is the manual. I am out of PIO boards atm, but can order some more. https://drive.google.com/file/d/15R1uQmP-oI5PkzhXWM9ldhylExr0w4yA/view?usp=drive_link

Yes as Slice is purely a passive tester and cannot drive its outputs. Those 16B boards are a pain as you point out. I had to make ribbon extensions to test CPS1 mainboards for the same reason. It is best to keep them short so you can stack the boards in reverse order. Slice with just the...

Yes, I can. I use the same Slapstic patches in my Atari System 1 multi cart (https://forums.arcade-museum.com/threads/atari-system-1-multi-cartridge.479793/) Biggest problem I see on your cart is that you are not replacing the Proms at 5A & 6/7A. These control the Palette & GFX bank switching...

Better question is why not! If I split out all the patches into individual files from my latest V14 version it would be over 2000+ files and be difficult to verify if any files have been corrupted until you tried to use them. Also my patcher will patch and combine files to generate new rom files...

Here is a link to my google drive with a copy of my lastest Patcher version: https://drive.google.com/file/d/1yt0aONAzfLiEYH0RrzNc0ZzvibeOrZ_E/view?usp=sharing As for getting rom sets to work on different cart versions it isn't that difficult to do. Just use the Mame source file for rom...

Choplifter is not a System 1 game! It's a System 2 and uses the enhanced tilemap custom IC. The only 2 standard system 1 games not on my multi atm are Block Gal & Water Match. I may well add these into my rom maker so they can be selected into one of the 16 slots. Then there are the bank...

Quite correct, Slice is a passive tester and cannot drive lines. You can however test roms & rams to see what data is being read/written to them. You can also set address triggers when testing memory devices so that when that location is accessed it can grab upto 300ms of data. I have used this...

The square central daughter board is made by Sega and converts the earlier board set to 4 way scrolling from 2 way scrolling. The longer daughter board expands the sprite roms from 2 upto 4 and is needed for games with the extra roms. My Sega multi is finished and is working fine on a random...

Another common cause of these boards giving a static display like that is mask rom failure (L12/L13). The reset circuit actually works off 10.3v unregulated which comes into pin 4 of the power connector. Also it would be worth checking that you have a clock signal on the 68010 pin 15 and to also...

Interesting, I am looking at the Sectigo Individual Code Signing Certificates which isn't too bad for a 4 year deal. But it won't have pass the MS Smartscreen reputation filter and ultimately it still relies on someone trusting me not to have virused the program before I sign it.

I would sign my executables but there is a cost involved in getting registered and getting a certificate. I do however run a decent anti virus regime and am careful where I go on the internet or which programs I run on my development system. But I do agree it pays to be careful in this day and age.

Yes it is a proper Freeplay / Rolling Demo with my patch. You can select either HSS or Freeplay or both options when patching the roms.

Once you run it and set a folder you can either use auto detect on files in that folder to see if there is a matching rom set or you can use the drop down menus to see what games are available in the patcher. Once a game is selected you can then select a version as in most cases I have attempted...

When starting out with Slice I bought 8 different LA's. Most ended up being too limited on channels at high freq or low storage memory. Quite a few were noisy as well. For Slice I use the Digilent Digital discovery, it will do 32 channels at 200Mhz and grab upto 300ms of data with very little...

No. It is unlikely that the eproms are your problem. It will most likely be TTL chips.

There is one part of the circuit that I know can cause road issues and thats to do with the raster interrupt trigger but am sure the picture looked a bit different to your issue. It's shown on sheet 13 of SP-298 Road Blasters schematics. It's 8A & 9A (74LS30), 10A (74LS27), 10F (74LS161), 10B...

Just wanted to say that if it wasn't for https://scoresaves.com/ and Matts tag line "A High Score Save Kit will make you play your game more often!" I probably would never have started creating high score saving / freeplay patches.

See the attached V13 of my ArcadeRomPatcher :) I went back and took another look and found another way to add Freeplay. It really was, took around 20 hours total to do all the versions. The main issue is that it's the MCU that handles inputs and credits in the internal code and changing this...
