No surprise to me that there is something that I am missing.
I was failing so miserably that I decided tontrybit in mame on the laptop to see what was up and I get warning banners of roms missing (but only some of them,) checksums bad, and something else I can't recall.

I'm at a loss presently, so you may still beat me.

Not sure what version of MAME you're running, but it's working in MAME 0.262 and 0.238 when launched via shortcut, .bat file, or command line.
- Also tried it in MAMEUIFX 0.153, but it did not work.
- Looks like you need at least MAME version 0.225 based on changes to the names of the ROM files inside sinistar.zip -- see list at http://adb.arcadeitalia.net/dettaglio_mame.php?game_name=sinistar.

If you want to keep the original sinistar ROMs so you can switch back if you don't like the modded version, rename the original "sinistar.zip" to something like "sinistar_orig.zip".

Put the 90kB .zip file with the modded ROMs in your "mame\roms\" folder.
- IIRC, it's a merged ROM containing files for sinistar, sinistar2, sinistarc, and sinistarp.

Rename (or copy/overwrite) the modded ROMs file to "sinistar.zip".

*** Modded ROMs have different checksums than the originals so it will not run from MAME's built-in UI. ***

Launch from shortcut, .bat file, or command line with the command "mame sinistar" or "mame sinistar2" or "mame sinistarc" or "mame sinistarp".
- It will warn you that the checksums don't match, but it will still run.   :cheers:

Thanks for chiming in Scott!
I'll have another try.  Man, do I suck at this part of this hobby.
I believe I was using 0.278 but I could be wrong.
The ultimate is to be able to add these to my jrok board in the Sinistar repro cabinet so we'll see how I do with that too.

When I get some time, I am going to burn the ROMs for my Sinistar cab.

finally downloaded the code and compiled it..

very cool... i like a lot of the new additions.
the tail, and bar graphs...

i haven't played it much to see how the difficulty functions are...

but will be playing it more in the future.. i got good at the other
variations, and actually hit 300k a few times... but i usually average
around 150k most games..
