Indeed. Reading through that first link, I think it would be nice if a brief one-line summary of what each decapped chip actually does was provided in the table. For example, we all know the recent Toaplan chips enable sound, but what does the UMK3 security chip offer - more accurate emulation in some way, or is it entirely unnoticeable?
Without looking I'm sure all this is documented in the respective target system source, but I think a one-line layman's summary right inline with the chips themselves might help people quickly realize the value of what is being done here, and ideally encourage more people to help out.
