Victor RG-M1 Wondermega Full Board Recap & Laser Clean

Full board recap on this Victor RG-M1 Wondermega (JVC's branding of the Sega Wondermega), complete with a laser sled clean. Drew blood for this one; photo evidence in the thread. Everything works; the motorised tray is just waiting on a replacement belt.

Sega Wondermega HWM-5010 Full Restoration (2nd Unit)

A pig to take apart and put back together, but the end result speaks for itself. Both the Mega Drive and Mega-CD sides of this Sega Wondermega HWM-5010 are fully operational.

Sega Wondermega HWM-5010 Restoration (1st Unit)
