graphics: "WARN ge - signal (...) unknown behavior"

[gid15]

A still unknown feature of the PSP graphical engine has been discovered. The first game was "FlatOut: Head On", showing

Code:

77125 [GUI] WARN  ge - signal (behavior=8,signal=0x0) unknown behavior

A warning has been added in r1880 to display this new function. It would be interesting to retest some games with r1880 (or newer) and check if this new WARNing is displayed. Best candidates are games displaying very bad graphics (completely distorted or where large parts are missing).

Hykem has already done some research on this new feature, but it would help a lot to find games using it. If you find a warning "...unknown behavior", please post a test report, including a log file at INFO level.

Thank you for your support!
