I figure if anybody could help me It would be on this forum, so here goes...
So does anybody know if this could be rewired to have a controller plug? I would love to use this as a replacement to the original Sega Menacer, as it has a more traditional shape and no separate IR sensor.
P.S. The AtGames genesis does not work with the Konami Justifier or the Sega mouse, so that suggest to me that the genesis on a chip found on the plug n play menacer might be a better than the one used by Atgames
I used to have a Sega Radica v1 (with Sonic 1 and other games), and yeah, the Radica GOACs are far better than the emulation for AtGames, (They can be modded to have a cartridge port and play other Genesis cartridges too!)
so it didn't need the receiver ?
it could be interesting to see
1/ how they made this justifier/menacer combo
for internals, I found this

but if you could share chip id, etc... it would be more useful !
I found online a picture
of the internals for a Sega Radica v1. Cross-comparing this with the "Radica Menacer", visually, it appears:
*Board near muzzle is the Menacer hardware module. Was the IR sensor moved here instead?
*Boards near trigger are obviously the reload/shoot buttons
*Board near back is just the power/reset button
*Board with the AC jack in the magazine holder is obviously
the GOAC board
*On both GOAC boards is a chip with a sticker with some Oriental script on it. Both have 22 pins per side of the chip, which according to Devster's research page on the Sega Radica
, is the ROM chip with the game. Assuming the game on the Radica Menacer is the Menacer 6-game cartridge (it appears to be so on the packaging in the photo album), it should be ~3MB large. Devster was able to dump the Radica v1 ROM, so this ROM should also be dumpable via his Mask ROM pinout table. With the special hardware (and whatever changes Radica made to the menus), odds are it would be a new revision to the Menacer 6-game ROM
In terms of hardware, the key to modding the Radica Menacer to plug into a Genesis 9-pin DSUB would be in figuring out whatever protocol (Saturn control protocol?) is being used on that ribbon cable connecting the Menacer board to the GOAC board, determining the pin out of each wire, and rewiring appropriately to a 9-pin DSUB probably.

Although wiring (of Saturn peripherals to the Genesis) is doable pretty easily, you still need to add some logic (either hardware or software) if you want to achieve what you want to do :
2/ if they made change on the game to support it
Since there is a glob microcontroller chip on the Menacer board, there is probably extra glue logic hardware being used if the Radica Menacer is indeed a Saturn peripheral, and also special code to poll it properly perhaps. Only real way to know if the game code was modified and how is to dump the Radica Menacer ROM, compare it to a clean Menacer 6-pak ROM, and if changes exist, disassemble the changed code blocks.
Sounds like this would make for a fun hardware-based homebrew project
. Let us know when the Radica Menacer arrives and post some close-up pictures of each board module. (YouTube video too if possible; I've never owned one, so don't know what changes were made to the game.)
