SEGA Links

On my quest for TEH Dreamcast knowledge I fell over these wonderful SEGA related blogs:

I was hoping for a swift response to my question over at dcemu however I have had zero response so far? Which is a bit meh... I mean these guys clearly know what they are talking about, hopefully they are busy or enjoying the DC. Shame really as I kinda want to spend sometime there :(

Fortunately the crew over at ntsc-uk came up with a few options, them folks are diamond I tell thee!

DREAMS CRUSHED!!

Recently picked up a JAP Zombie Revenge, when it arrived I popped it into my PAL DC via the DCX boot disc.
Appeared to be fine, played the 1st mission no problems, but as soon as the episode 2 screen pops up I return to the DC menu screen? Disc looks fine, tried again and same issue :s

Thinking this was FAIL I fired up my JAP DC and tried again...
With this console the episode 1 screen came up after the intro FAMMYDODD'ed back to the DC menu? Whaaa!??!


So I then tried the rest of my NTSC-J games on the JAP console:
SFZ3 - resets wont play?
Biohazard 2 - dies after the intro movie?
PenPen - resets wont play?
All Revert to the DC menu screen?

Space Channel 5 - fine
Cap Vs Snk 2000 - fine
Soul Calibur - fine
F355 - fine
Daytona - fine
BioHazard CV - fine
Crazy Taxi - fine
Sega rally 2 - fine
Marvel Vs Capcom2 - fine

Wtf is happening?

PAL DC, so far has played:
(J)Cap Vs Snk 2000 - fine
(J)Soul Calibur - fine
(J)Daytona - fine
Giga Wing - fine
Gunbird - fine
Bangai-O -fine
Virtua tennis -fine

Dreamcast...

Back into the DC big time, picked up GIGAWING, DYNAMITE DEKA 2, BANGAI-O, GUNBIRD 2... Again!
Re-played CAPCPOM Vs SNK, MVC2, SFZ 3! All still pushing the fun and feelings of arcade'ness!
Oh and a M3H for VIRTUA TENNIS pure fammydodd :(

I know what I'm missing, but what do you think?
