> FWIW you could use a BIOS option to load one arrangement of PROMs or the other and avoid the need for a clone. Sounds good, will do that. Thx!!

> Should the alternate PROM arrangement be added to all the sets, or only to the ones it’s been seen on in the wild? I've added it only to the...

> Have both bootleg versions really been seen with both PROM arrangements? That would be pretty surprising. Ah! You’re right, I’ve only seen this arrangement on original Irem/Tecfri/Williams. Should it...

> Yes, I wouldn’t add the option to the bootleg sets if they haven’t been seen with both arrangements. Done, thanks!!

> Please look at the overall diff. You’ve “restored” the PROM labels on the wrong bootleg. Now `travrusab` and `travrusab2` have their PROM labels swapped with each other. Ah! Yes,...

> In the future, please check your changes carefully. It’s far too easy for errors to get in like this, and noticing/fixing them after the fact is always far more...

Cannot tell... The PCB was modified on many ways. ![RUID2d593c87cf744106a2dddc4480b1b657](https://github.com/mamedev/mame/assets/5889052/be21824e-af73-48b5-a56f-3f15d1fb9cfc) ![RUIDa2441f8dfbdf47ca8cd1738ba0030674](https://github.com/mamedev/mame/assets/5889052/834c4a31-8eee-4b40-b29f-26ea7cee81ee) ![RUIDbff4c3210639469d9a964f0345a0d017](https://github.com/mamedev/mame/assets/5889052/8efed3b0-9c97-438f-bc63-4e3924698dab)

Hi! If colors are wrong, it's not a matter of changing the PROM, but decoding it properly, as we dumped the PROM from the actual PCB. Thx. ________________________________ De: 2k2...

I'd appreciate some help with this one. There's a glitch that happens also on real hardware (real hardware: https://youtu.be/By7Xi5jf2Qc), so, one tilemap ROM must be bad, but I cannot tell...
