Messiah 2 clone ? (doubt it, but it works)

[mud ver.2]

I installed two "Messiah 2" clone chips yesterday on two 39001 ver.7's. I guess the chips came from http://www.the-console-corner.com/the_messiah_2.htm

They certainly aren't messiahs, but they work ok. Booted all my Ritek DVD-R backups. But only my quality CD-R back-ups booted (ie - TDK, Verbatim, Phillips). Memorex back-ups gave the RSOD.

GT3 DVD-R - OK
Dead To Rights DVD-R - OK
LOTR The Two Towers DVD-R - OK
GTA Vice City DVD-R - OK

I let the Vice City intro play for a bit, didn't freeze. Played around for a while, didn't freeze. I'm not sure where the Magic 3 freezes.

Anyone know what they really are ? Apple chip clones maybe ? Matrix ?
