Hi,
I've patched all Sega System 32 games in order to desuicide them or make conversions:

Cheers.
[EDIT]
I'm going to release the files here, reason I was selling them was to fund some projects but DS proposed to send me the hardware I need so I can move forward on my projects and everyone can enjoy the games.
Here's the list of the protected romsets:
- arescue: Air Rescue, suicide module battery powered
- arescuej: Air Rescue, Japanese version, suicide module battery powered
- arabfgt: Arabian Fight, security module, non suicide
- arabfgtu: Arabian Fight, US version, security module, non suicide
- arabfgtj: Arabian Fight, Japanes version, security module, non suicide
- brival: Burning Rival, suicide module battery powered
- brivalj: Burning Rival, Japanese version, suicide module battery powered
- darkedge: Dark Edge, suicide module battery powered
- darkedgeJ: Dark Edge, Japanese version, suicide module battery powered
- dbzvrvs: Dragon Ball Z V.R. V.S., suicide module battery powered
- f1lap: F1 Super Lap, suicide module battery powered
- f1lapj: F1 Super Lap, Japanese version, suicide module battery powered
- ga2: Golden Axe 2 The Revenge of Death Adder, security module, non suicide
- ga2u: Golden Axe 2 The Revenge of Death Adder, US version, security module, non suicide
- ga2j: Golden Axe 2 The Revenge of Death Adder, Japanese version, security module, non suicide
- sonic: Segasonic, suicide module battery powered
- jleague: The J.League 94, Japanese version of Super Visual Football/Super Visual Soccer, suicide module battery powered
- jleagueo: The J.League 94, Japanese version of Super Visual Football/Super Visual Soccer, alternate version, suicide module battery powered
Most of the time only one ROM has to be updated for the game to work without the security/suicide module. However checksum would be wrong in the test menu so a second ROM has to be updated just to modify the checksum value.
And the files (in progress, files are scattered all over my hard drive):
Air Rescue:
This game is supposed to be played on a twin cabinet. However MAME's devs have found a way to make it a standalone game. Only difference is the title not being cut in half during intro (as originally half is displayed on each of the 2 screens).
Protection can be reduced mathematically to a multiplication by 4 which can also be translated in assembler by a simple 2 bit left rotation... So weak.

Dark Edge:
One of the protections (for the 2 player mode) expects the module to decrease a counter in RAM and when zero is reached it sets a trigger. I think this is where Asure got stuck.
Thing is there isn't any real check that the counter was decreased by one on each cycle so you can fool it but just setting it to zero and setting the trigger to 1 in the same cycle (see my blog for more details).

The J.League 94:
Weird enough other versions of that game (Super Visual Football and Super Visual Soccer) don't have a security module.
Also it's quite funny the less desirable game has the strongest protection (I had to include the protection algorithm in the program ROMs where I could simply nop or modify conditional branches for most of the other games).

This should cover at least one version of each game for now.
Happy New Year 2018 guys
