there are no proper idbs for r2 and r4 sa:mp, these versions are barely used and don’t differ much from the more popular builds.

to put it bluntly:

- the r2 version is basically the same as r1, there are almost no changes

- same story with r4, it’s effectively the same as r5 (or r3, i might be mixing them up)

when i needed to quickly find an offset for r2, i just opened two ida pro instances: one with r1 and one with r2, generated a signature in r1 and then searched for it in the r2 idb.

IDB for SAMP 0.3.7-R1, 0.3.7-R3-1, 0.3.7-R5-1
