Magic 3 and PS2 versions

[pico996969]

I was wondering something, and i'm thinking the only people that would be able to help are the people who can actually understand the mumbo-jumbo i see when i look at the magic 3 code....i've done alot of installs of magic 3's, and i notice the v1,2, and 3 ps2's seem to not boot as well as 4,5,6,7 ps2's...i have done tests replacing the lasers...re-installing, just about everything, and on some consoles it just won't boot past 80% of the time, wheras most v5's and 7's i've done boot 100% all the time....is the code for the v7's more complete than the v1's... i mean did they work more on every little bug to make it this 100% or is it just me....
