Just a heads up... I already have Robocop (U-Pro) updated with FizX and PinEvent, and my typical other updates (as well as some other tables already updated and in progress)... that will be released soon enough. Read the PM I sent you for more info.
As for the error.... if you get that, try to rename the Table name in the editor to something else. I had the same thing when updating this table as well.
The name ROBOCOP is probably used elsewhere in the table and is messing up the xbam.table command used in the update code. After I renamed the table name (in the FP Editor) to something else, it worked fine after that. Something to keep note of for everyone in the future when updating.
As for ROM, he has been out of the hobby (and the sites) for YEARS now. The last time he responded was when he saw my mod of his MOTU table on my YT channel, and he said he loved seeing new stuff like that added to this tables (and he was amazed people still play them). He never voiced any issues with mods of his tables before.
Myself, I'll be releasing ROBOCOP (UPro, PinEvent Lite, FizX) soon enough. This is a complete table overhaul like my other updates usually are. More are coming!
