>Look at this beauty, all corny and cool looking
Good find. It's a bummer that the photos don't show a decent closeup of the pcb rom locations because that part is currently not complete yet for the TenPlay 2.11 bios version.

ROM_LOAD16_BYTE_BIOS( 3, "gcp-1-lo",
Unsure if the current rom file names could also use renaming to match closer to what the labels indicate in the photos.

Thanks for pcb photo.
for the -lo roms it is .u16, .u17, and .u18 .....which is a good start for documenting the rom ic locations of the 2.11 version.
What is still needed is the "u" locations for the -hi roms for this 2.11 version. If you can post a closeup photo of the -hi roms and their specific locations and add it to this same thread topic, thanks. I will forward this to someone and they can update the rom location info in the source code....hopefully before next release.

This is my guess:
ROM_LOAD16_BYTE_BIOS( 3, "gcp-1-hi", 0x000000, 0x10000, CRC(67d44523) - U16
ROM_LOAD16_BYTE_BIOS( 3, "gcp-1-lo", 0x000001, 0x10000, CRC(65d9b9cf) - U11
ROM_LOAD16_BYTE_BIOS( 3, "gcp-2-hi", 0x020000, 0x10000, CRC(1d7594ae) - U17
ROM_LOAD16_BYTE_BIOS( 3, "gcp-2-lo", 0x020001, 0x10000, CRC(e776198d) - U12
ROM_LOAD16_BYTE_BIOS( 3, "gcp-3-hi", 0x040000, 0x10000, CRC(3e7364be) - U18
ROM_LOAD16_BYTE_BIOS( 3, "gcp-3-lo", 0x040001, 0x10000, CRC(87229e0d) - U13
Why be contrary?
Because I am familiar with PCB layout software. The "U" designations are always near the notched side of the ICs so the parts stuffers have a reference to keep from putting the IC in backwards. (Yes, years ago, actual humans stuffed PC boards with components - not robots)
The PCB printed tags for U11, U12, & U13 are not visible due to the angle of the shot. (Well, the top half of the lettering is, but it's hard to see it due to the glare from the flash) So why do I think they are numbered that way? - there is a U10 visible below what I think is U11, and there is a U14 visible above what I think is U13.
I think U23 and U24 belong to the unpopulated ICs and U25 belongs to the SRM2064C.
In this orientation view, the ICs are numbered from left to right, bottom to top.
So I think the hidden-from-view/poor visibility IC tags follow this pattern.
Of course a better shot would be actual proof, but if that is not possible, I think the IC numbers I guessed are the best representation.

>Looks like U23, U24, U25.
Hopefully another photo with closeups of locations can be placed here so that helps with further cleanup of arcadia.c file

I hope the contributor can help out a bit more with better closeup of photos of ic locations of the chips.

Gyrovision told me a couple past stories in his work experience where repair techs had accidentally set the roms in incorrect location because they didn't have reference guides so some pcbs were beyond repair after the accidental oversight. A reason why it is good to see BrianT always updating rom locations in MAME source when possible.

Hi
Sorry for the late response but here are some more pics.
And what is going on here ?
