Quoted from Soulrider911:Anyone tried this ROM with the PinballSP video mod? Wondering if it will work...
Holomodsp has always been compatible with the Soren Rom Rev5, as well as with the L-4 (and probably even L-3). https://pinside.com/pinball/forum/topic/hologram-mod-for-creature-from-pinballsp-is-under-development#post-3602030
Since the first firmware release, the Holomodsp has already been tested with both Roms, and all necessary firmware changes have been made to support the Soren Rom.
If there is a version later than Rev5 I would check it out, but I don't think it will affect the switch matrix or lamp signals. I seem to remember that the differences were in the digital signals of the data bus that deliver information about the status of the lamps, flasher and coils. These differences are present between the older versions of the WPC89 system and the later WPC-S and WPC95, it seems that the newer versions handle the lighting of the lamps more efficiently avoiding the ghost lighting of some lamps.
If you haven't done it yet, I suggest you update the firmware of the green board (Raspberry), because it greatly improves the boot time of the product to about 15 seconds, less than half of the first versions.
