Should it be the 'code' in HEX or the 'code + 8000' in HEX?

First, I don't own a 2K/3K/Showstopper - I own 4 5XXXs (3 Lifetime; 1 'Spare Parts'). I used dontcareavs's code on AVS to get my 2 FREE DC-50Xs working. Thanks!

Since I went through the 'exercise', I'm also glad to try to help anyone else attempting the task, even 2K/3K/Showstoppers. Until now, no one with a 2K/3K/Showstopper has reported any success. Enter ReplayTV Guru Mikeyboy.

Mikeyboy edited Robman's C0015_OBJ into S0392.OBJ and IT WORKED! I asked him to try Robman's C0015_OBJ and IT DIDN'T WORK?!? It appears to be the understanding that you can rename the file / change the 'Identifier Bytes' (2 & 3) freely thus:

• 01 88 for 0392
• 00 0F for 0015
• 01 14 for 0276
• etc...

Which leads to my question:

Why does Robman's C0015_OBJ and the 'stock' C0015_obj from replayir.zip use 08 0F, which Mikeyboy confirmed doesn't work?

Examining a few other 'virgin' files from replayir.zip:

• C0160 is all SPACES except for 00 A0 in bytes 9 & 10
• C0276 has 00 14, which looks correct (i.e. HEX-to-DEC)
• C0525 has 02 0D, which also looks correct

So, why did Robman and dontcareavs use 08 0F for C0015?

The particular bit that you are questioning is used to determine if the first byte of the protocol id should be 00 or 01. So, if the protocol being used is greater than 0x00FF then that bit will be set and it would appear that the hex is "code + 0x800".

The hex in question was generated by RM, it wasn't created by hand, so if you have found that this bit should never be set, RM may need to be changed to reflect that.
