Puma Street Soccer PPM

Latest revision as of 15:39, 20 September 2025

Puma Street Soccer is a video game developed by Pixelstorm. It has an associated .PPM texture graphics format.

P.S.S. PPM is a variant of Netpbm binary PPM (P6) format.

It's not certain that this format is specific to Puma Street Soccer, but no other use has been found.

[edit] Format details

P.S.S. PPM is structurally the same as Netpbm PPM, except that the signature is "PX" instead of "P6". However, the images are apparently not interpreted in the same way. One possibility is that they are deliberately obfuscated.

[edit] Identification

Files start with ASCII "PX", followed by a newline (0x0a).

In practice, the second line always seems to be a comment line. The following examples have been observed:

# Created by Paint Shop Pro
# Created by Paint Shop Pro 5
# Created by Jasc BatchMaster
# Created by Jasc Image Robot

It seems likely that these comments are misleading.
