TYRIAN for PSP

[Thargalt18]

Thanks a lot
Will it work without the eloader ? on slim ?

I did it twice just to confirm that it wasn't a fluke or anything, but there was nothing specific going on, it was just right before the boss is supposed to come, it says **Large mass detected ahead**, then goes to blue screen.

I was able to replicate it too.. it seems that there is a problem with following code chunk:
loudness.c: void JE_multiSamplePlay

                for ( ex = 0; ex < SAMPLE_SCALING; ex++)
                {
                        channel_buffer[chan][(i * SAMPLE_SCALING) + ex] = ((SAMPLE_TYPE) ((Sint8) buffer[i]) << 8);
                }

I am sure it will.. the reason I did not release 3.xx kernel version is because of compatibility..
All PSP users should be able to run 1.0 kernel versions (through some tricks) while not all psp users can run 3.xx kernel version..

Very nice :thumbup:
It runs very well on my PSP Slim 3.71 M33-3 under eLoader v1.000 from Team Noobs

I just downloaded, unrared and tossed the Tyrian folder into PSP/GAME and ran E-Boot and selected Tyrian an Presto

eLoader v1.000 link: http://www.noobz.eu/joomla/component...artdown/id,22/

I checked out the source on friday morning.. don't recall the revision though...

just making sure you're patching in the latest revisions and bugfixes

Edit: Disregard this entire post. It won't work if you try running it from under iRshell thru eLoader :P


PDG, how did you make it work?

I did all the same things, ran eLoader 1.0000, then the Tyrian folder thru it...

All it does it freeze on a black screen, only taking the battery out helps. Tried all of the alternate eboots also.

                }

I believe I have spotted the same sort of bug. It may be the same one but it also saved the coordinates of the bug. I'll post them here they may help.

Are you still talking about Stargate? Because that was fixed as of revision 625, and the error was in tyrian2.c

Assuming you didn't find a completely different bug at the same level too.

[deniska]

well, my exception handler points to the highlighted line.. so this seems to be a different bug.. I'll see if I can replicate it in the windows build..
This could also be something, specific to psp architechture
