FREELOAD (+clones) 

--------------------------------------------------------------------------------

Genuine Freeload can be found on... Barbarian, Combat School, IK+. Platoon, Robocop, 
Slapfight, Wizball etc.. 

Clones of the Freeload file format can be found on.. 180, Alleykat, Paradroid, Angleball,
Kromazone, Spore, etc.. (see notes below). 

--------------------------------------------------------------------------------

Threshold : $0168 (360) clock cycles (TAP byte $2C).
Bit 0 : $24
Bit 1 : $41
Endianess : MSbF 
Pilot byte : $40 (*128)
Sync byte : $5A 

Then...

2 bytes : Start address (LSBF) 
2 bytes : End address (LSBF) 
n bytes : Data
1 byte : Checksum (0 XOR all data bytes) 

Notes:- 

This exact same file format is used by the "Graftgold" and the "180" loaders, also by 
Mastertronics "Invade-a-load" and "Load-n-play" loaders which differ only in that they 
use 64 pilot bytes instead of 128.
