Assembly Offsets

This list of hex addresses shows where each different type of componet is processed in the executable. Knowing where these offsets are allows for quick modification using OllyDbg or DouAsm, or injection with the modloader.

TSC offsets

Function Offsets

This list was initiated and collaborated by S. P. Gardebiter, Runelancer and GIRakaCHEEZER. It was later updated by Noxid. Some portions of this list are not completely covered and have unsure responses, use at your own discretion if you’re feeling experimental!

This list is over 1300 lines long, and for obvious reasons, if included inline, would bloat the page, so it has been moved to a downloadable text document.

Many of the functions described in this list can be cross-refrenced with CSE2, the cave story engine decompilation to see what they do and exactly how they do it.

Assembly Compendium

Noxid’s Assembly Compendium contains a plethora of Assembly offset findings and other various neat doohickeys. Unfortunately, not all of the given information is correct and some of it is “unsure”. As of now, with some of the new documents that are forming, this compendium is outdated in some areas, but had stood the test of time for many years. Use at your own discretion!

Like the function offset list above, this file is also massive (2291 lines for those of you counting at home). Likewise, it has also been moved to a downloadable text document.
