This program enables homebrew and downgraders to be run on 3.03 using the original version of GTA.8 i7 @% r1 e2 N4 R+ ~

- As mentioned before, homebrew has to be in prx format, at least atm. Furthermore, the main prx, the one in
5 \. S) s. q4 H6 p2 x  the pbp, has to be an user prx. However this user prx can load unsigned kernel modules from
7 [) G, S1 L: R5 n) V. u  the memory stick, allowing kernel mode apps.9 x" [5 q; w- V6 d& \" v2 J5 i

- Try to use USE_KERNEL_LIBS = 1 in your kernel prx's. In 2.XX, the separation between user( g6 o  E, W# r- Y
  and kernel mode is higher than in 1.XX. 7 j  J8 J! j: t7 w. l
  Some functions in "*ForUser" are now totally separated (different address) from their
