Sega — Wondermega
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
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. Later fitted with an Oleg Endo RGB kit: a tap board on the Sony CXA1145M encoder, the factory bodge wire and stock S-video port removed, and a Saturn-style DIN in their place with audio, composite and power wired across. Clean RGB at last, without the artifacts and ringing of the stock composite and S-video outputs.
