I have a cart by Crashman on this forum viewtopic.php?f=11&t=959&hilit=crashman, will the diagnostics be significantly different to those on that cart, if so I need one :)
Collector of old Atari things:
800XL + Ultimate 1MB, 2x 1010 cassette, 1050 + Happy mod, 65XE (128k +APE Warp) & XC12, SIO2SD, 2600jr, 7800 and Lynx II
Atari 520ST (1Meg), 1040STF long button floppy, 2x 1040 STFMs + Gotek, 2x 4160STE with 32Mhz booster, ROM switcher, Mega ST1, Mega ST4, not to mention various bare ST boards for testing including a PAK 68/2 :)

The cart I am doing has all the basic Atari diagnostic carts, plus will have both versions of YAART & GB6.

K, here's a very alpha GUI version of my Powershell script. Make sure you have the files to be converted in the same directory as the executable.

You can select either 64KB or 128KB. I have not coded any safeguards if the file is larger than the image you are converting to. Expect crashes. Otherwise it works just fine.
:bravo: :thanksyellow:

SysInfo and GemBench work great on my diagnostic cart, thanks! I have not analyzed details of your 16-bit ROM cart, but if you are making a proper use of ROM3/4 lines you may use both 64kB and 128kB ROMs. Yet over-complicated jumper settings tell me that you are switching between 64/128kB cart modes. If you have 8Mbit Flash EPROM, then you may sacrifice 64kB for every 64kB ROM, but instead you could use convenient rotary encoder to select ROM number (like in one from Olivier Gossuin). If you are afraid of some address decoding issues, you may just fill second half of 128kB slot holding a 64kB ROM image with a second copy of the same 64kB ROM image.

Also crashman's cart had a rotary encoder to select ROM:

Thanks for the confirmation in real life.

Rotary is good for simple binary selections but I am selecting 128K, 64K, 32K now. Its why the jumper settings are getting more complicated.

Yes I did. I just wanted to see if I could do it in Powershell as a challenge to myself.

Hopefully this will be the last design of this board!

I need to create a new ROM image and build it up...
