GB Ancient dev tools ISDMG and ISLINK found in recent first party source leak

[MegaBoyEXE]

There are now 2 versions of ISDMG (v1.21d from 1993 and v1.21f from 1995) and 1 version ISLINK (1.20e from 1993) that were found inside a recent first party source code leak.
There is also official gui tool ISX2BIN, and internal beta emulator (not very accurate, but seems to support some obscure devices like GB Mobile)

If anyone have more GB stuff, I'm insterested too, as an emulator writer.

Where is it possible to find the full leak ?
