IRION (Exerion) PCB found - possibly Exerion PROTOTYPE ?

I have found a PCB with an Exerion Clone (?) or Prototype (?). Game title is IRION. See the attached pictures.
Anyone seen this before ?

The PCB looks different to the 2 PCBs I know of, the Jaleco 1-board and the 2-board versions.
The PCB seems to be limited in comparison to the Jaleco boards.

Gameplay is only different by the not moving background. Otherwise the game seems to be the same.
It shows "---S 1983 11---" instead of the "(C) 1983 Jaleco" string.

I have not seen this to be emulated in MAME in version 0.192.

Of course, if you have the means, dump what chips you can and compare with current MAME is possible. There is always chance it is more than a simple titlescreen hack bootleg.

Re: IRION (Exerion) PCB found - possibly Exerion PROTOTYPE ?

I have dumped all 6 eproms.
All 6 are of type 2764.
I have named them simply 1.bin ... 6.bin.
See attached zip.

Using "Hamster's Online Rom identification" tool I have found that only 6.bin is associated with a known rom, see the following table:

game desc rom name region offset
exeriont Exerion (Taito) exerion.11 gfx2 0
exerionb Exerion (bootleg) exerion.11 gfx2 0
exerion Exerion exerion.11 gfx2 0

All other roms ( 1.bin - 5.bin ) are not to be identified by using Hamster's tool.

I've forwarded the roms to the Dev Team. If there are more question about it, someone will likely reply otherwise expect to see it added to MAME soon.

Thanks for your effort!

Robert,
if you need more information, e.g. high-res pictures of the PCB or else, let me know.

Is it possible a conversion to something closer to Galaxian hardware? (hence the more basic starfield, lack of background, lack of 2nd CPU etc.)
