I don't know about the standalone cracks but if you have the Goodset roms some of the patches are included there.
I have not tried any of these patches but this is what other people said should work:
For Jet Force Gemini look for roms named "Jet Force Gemini (E) (M4) [f1].z64" or "Jet Force Gemini (U) [f1].z64".
And for Donkey Kong 64 look for "Donkey Kong 64 (U) [f2].z64". This patch includes both the boot crack and the SRAM hack (which changes save type to SRAM). so remember to force SRAM before booting.
The Banjo Tooie patch can be found at
http://www.64scener.com/ but Krikzz included it in ED64 OS and it's applied automatically so you don't really need it.
