Wrong platform 
Segasonic and Spider-Man are system 32

Did you submit it to MAME? If not, may @MetalliC can point you in the right direction...
usually I just tell RTW
, is there a more official channel I should be using?
Just for info, please...
I just acquire an Ace Attacker control panel and since i like sports game so much, what do i need to perform a conversion from tetris (or any other system 16B) to Ace Attacker?
If this is possible of course

Well, I can get you halfway. Ace attacker only came on one rom board it looks like - 171-5358. here are the games that ran on the board. It's important to note that many games ran on many boards, so you need to find a 171-5358 romboard.
I am not sure if Ace Attacker is encrypted, so you may just be able to burn the roms and boot it up. If your previous board used an FD1094/FD1089 for the CPU you'll need to swap in a normal 68000-10mhz cpu. I also don't see the jumpers documented, so your best bet is trying to find a photo of one that's working and use those. Otherwise you could find another game that uses the same rom sizes, and start with those jumpers.
Thank you for the explanation.
I'll try to see my Tetris board and check if it's a 171-5358, to start....
This has been tripping me up a lot recently. Is there a way to determine in MAME source or looking at the ROM board etc. with 100% certainty if a chip should be 27c1000 or 27c1001?

Not that I'm aware of. The main program ROMs on every board I've seen so far has been 27C1000 - so I would say with certainty that main program ROMs if they're not 512 are 1000
That whole era is a pain. I've had a couple of boards I've been tearing my hair out trying to work out why there's no sound/garbled sound and it turns out even though it's silkscreened for one type it uses the other.
(Yes it should've been one of the first things I tried, but if they're marked for a chip I'm going to assume that's correct)

I just got the Time Scanner board.
I can't find unprotected roms to burn to do this.
So i asked Apocalypse about this....
Here is the Time Scanner board i want to use for conversion:
I want to use Ace Attacker with this
I really hope it could be done...
Looks like the right romboard and it's already using a regular 68000 CPU. Have you tried burning the roms for Ace Attacker? The reason you can't find decrypted sets might just be that they were never encrypted to begin with. The romset in MAME might work!
You'd have to burn all the other chips anyway. Only A5/A8 would be different from the MAME set. Give it a try.

So i have to use the same eeproms on the romboard and burn Ace Attacker mame roms into them, ok.
What are A5/A8?
Ace attacker use the FD1094 encrypted CPU module hence he can't perform this conversion (by burning the program ROMs from MAME set and using a 68000 CPU) unless he has the module or he is able to decrypt the code himself (or pay someone to do the job...)
Very bad news.Ace attacker use the FD1094 encrypted CPU module hence he can't perform this conversion (by burning the program ROMs from MAME set and using a 68000 CPU) unless he has the module or he is able to decrypt the code himself (or pay someone to do the job...)
I can pay of course if someone could do this....
Since the original board seems to be nearly impossible to find.
Try to contact Mark at Reroclinic:
http://www.retroclinic.com/leopardcats/decrypt/decryption.htm#decrypt
Or Chris a.k.a. JunoMan :
http://www.segaresurrection.com/
Although the decrypted ROM set is not listed, they can prepare it (paying them obviously..)

Thanks i'll try with them.
But from what i see, even Time Scanner is not listed there.....
This means that i'm the only one to have the decrypted set?
Accordcing to MAME sourc there is only one revision of Time Scanner and it's encrypted with the use of the FD1089B (317-0024) CPU module.So, since you have a regular 68000, you could have a not encrypted code from factory or a decrypted one from someone (or from factory too) ot someone simply took the module and put a 68000.Is the board working?It would be interesting if you could dump program code, maybe you found a new revision that I can send to MAME if you want (I'm part of Dumping Union list)
Yes the board is working perfectly.
If you let me know what i can do....
If you have an EPROM programmer, read the devices from A1 to A6 on ROM board.According to MAME source they should be labeled in this way:
ROM_REGION( 0x40000, "maincpu", 0 ) // 68000 code

Or, if you can, dump them all.Thanks.
