Half Byte Loader SVN Changelog:
r98
JJS
- Added Nymphaeas patch that allows to exit HBL to the XMB by using the HOME
exit menu ( http://advancedpsp.tk/foro_es/viewtopic.php?f=37&t=1046 )
- Added code to get additional syscalls using the stubs of utility dialogs
loaded into p5.
-- This means sceCtrlPeekBufferPositive can now always be used and the option to
override it is now obsolete for all 6.20 users.
-- Also all relevant sceIO* functions should be perfectly estimated now.
- Fix for issue 43 (crash on start from MS on the GO). Kernel dump is now saved
to ef0.
- Fix for issue 306 (control issues). Hopefully fixed by replacing the
sceCtrlReadBufferPositive call with sceCtrlPeekBufferPositive.
- Corrected 5.70 nids files. Thanks n00b81!
- Corrected scesuspendforuser.nids for 5.xx and 6.xx.
r99
wololo
- fix a bug introduced in r98 that prevents syscalls from being correctly
estimated on pspgo 6.20 (error reading kdump)
