I would look at mame source between gals panic su and gals panic s2
- Thread starter djsheep
- Start date
This is the best mapping I could come up with based on the mame driver:
ROM4 <-> ROM2
prg
u6 <-> u10
u4 <-> u8
spritegen
u21 <-> u24
u20 <-> u20
u8 <-> u17
u32 <-> u32
gfx2
u17 <-> u16
u9 <-> u13

u3 <-> u7

plds

Checking my 2 versions of galpanis, I can confirm (in blue) some of the mappings deducted by @twistedsymphony (thanks)This is the best mapping I could come up with based on the mame driver:
ROM-3-BOARD <-> ROM-2-BOARD
prg
u6 <-> u10
u4 <-> u8
spritegen
u21 <-> u24
u20 <-> u20
u8 <-> u17
u32 <-> u32 (there is no u32 in ROM-3-BOARD and u32 is a 74LS374 in ROM-2-BOARD)
gfx2
u17 <-> u16
u9 <-> u13
gfx3
u3 <-> u7 (not populated in galpanis neither in ROM-3-BOARD and ROM-2-BOARD)
¿¿ u5 ?? <-> u18 (not populated in galpanis in ROM-2-BOARD) (Cyvern uses this position: U1
ymz
u1 <-> u4
plds
?? <-> u9 (There is no pals in ROM-3-BOARD, seems they are integrated in big SMD at U2)
?? <-> u11 (There is no pals in ROM-3-BOARD, seems they are integrated in big SMD at U2)

I should have noted.. the mapping I had in my post is for
ROM4 <-> ROM2
ROM3 isn't mentioned in the mame driver unfortunately. but based on your mapping it seems it's similar to ROM4
there is also a "ROM-BOARD" (with no number, essentially ROM1 I guess) that seems similar to ROM2.
I would think the ROM labels should give you some idea of which position they map to though.
Here's the best picture of a cyvern cart I could find. the ROM labels match the ROM positions in MAME (for ROM2-BOARD) from what I can see.

OK, maybe you have a typo in:
u32 <-> u32
and, should it be?:
u32 <-> u22
There is no U32 in ROM-2-BOARD
Anyway, here is the mapping I figured out from comparing my two galpanis cartridges:
ROM-3-BOARD <-> ROM-2-BOARD
prg
u6 <-> u10
u4 <-> u8
spritegen
u21 <-> u24
u20 <-> u20
u8 <-> u17
¿¿ u22 ?? <-> u22 (Unpopulated in galpanis)
gfx2
u17 <-> u16
u9 <-> u13
gfx3
¿¿ u3 ?? <-> u7 (Unpopulated in galpanis)
¿¿ u5 ?? <-> u18 (Unpopulated in galpanis)
ymz
u1 <-> u4
u32 <-> u32

if there is a typo it's in MAME... this was based on the MAME driver for Gals Panic 2 which shows ROM gs210300 in position u32
maybe this exists on the ROM 1 board?
If I have time tonight I'll crack open all of my carts to see what's what. I have a nearly complete collection of carts for Super Nova (just Missing Tel Jan) so I'm bound to have every cart revision in there.
I went through my carts and I do indeed have all 4 ROM board variants in my collection.
this is the mapping between the 4 cart variants as best as I can figure
* = educated guess based on position on the ROM board and MAME info.
N/A = not available

I can confirm your guesses about Cyvern. I managed to make a conversion using a ROM-3-BOARD, following your mapping table.I went through my carts and I do indeed have all 4 ROM board variants in my collection.

(Ignore second empty socket. In that moment I was not installed that eprom)
U18 rom from Cyvern used in ROM-2-BOARD should be installed in U3 position of ROM-3-BOARD, as well as other roms based in your mapping table. Thank you very much!
Thanks for confirming!

Same thing happened with me on two occasions. Not super bummed as I personally think the game is trash but I was converting it for someone else.Just got a few carts to make a Cyvern and Sengeki Striker, the Puzz Loop I received is a Rom 2 board.
Am I out of luck making a Sengeki out a Rom 2 board, it needs 4 sprite roms and there is only 3 on a Rom 2 board.
Anyway I made these in preparation.
I actually made some alternate labels for these two as well, I'll attach them.

yeah, so Sengeki need any board type other than ROM2, but I believe you can use ROM2 for CyvernJust got a few carts to make a Cyvern and Sengeki Striker, the Puzz Loop I received is a Rom 2 board

I'm not the biggest fan either, I have a gals panic S and Jan Paradise but they are both Rom 2 as well.
I wonder if you could merge the 4 sprite roms into two 8mb files and burn them to MX26L6420 chips.
I downloaded the Rom 2 board Puzz Loop rom, It has a 4mb file for the spites and the Rom 4 board roms has 3 files for sprites so my guess is 3x1mb rom files.
There doesnt seem to be any jumpers except for the eproms, I know how jumpers work on neo geo for rom sizes but no idea how this would work.

I've seen this offer [FS] Kaneko Super Nova System motherboard with Puzz Loop cart $165 (USD) Shipped
this cart is ROM2 or ROM4 board?
is it good donor for cyvern conversion?

puzz loop came on all different board version. But AFAIK any board version can be made into Cyvern. It's sengeki striker that's the problem.
IMO that $165 set is overpriced. In Japan you can get a mobo for 75 and puzz loop cart for under 20. Even with shipping it would be less than that 165 lot.

Im just starting on my Cyvern conversion, why are we feeding 3.3v to pin 1 Write enable on the 29L3211?
Its not connected to anything on the pcb, I thought it was only used when programming?
Pardon my ignorance.

Pardon my ignorance.
MX29L3211 are EEPROMs that could be burned many times by setting pin 1 to "low". We need to put it to "high" by ourselves in order to set them to "read only mode".
As original roms from kaneko cart are not eeproms but mask roms, that pin is NC (not connected) and because of that it's not need to be set to "high" by the pcb.
welcome!
Nice label btw. Did you use the file you uploaded some days ago and posted in your previous post?
Green from inner logo looks brighter than the label you uploaded.
