Re: pspsdk strncat broken
I've been having some trouble with peldet running out of memory when using newlib, so I decided I'd try the pspsdk libc. (I seem to recall someone saying that newlib mallocs the largest amount of memory it can and then just assigns from there?) For the record, PSPSDK's libc uses the same _sbrk() th...

After doing some thinking and talking with the fellas on #pspdev I've decided to drop 16:9 as a playfield hack and implement 4:3. The display and playfield are now exactly the same as the original game. It was a mistake for me to ever hack up the playfield in the first place. I may at some point add...

It seems the only mode where there is a speed difference is Normal mode. I haven't played the original version of the game so I'm not certain if the other play modes have specifically different speeds for the ship when toggleing laser off and on. The gameplay is no different than the original versi...

If a game is developed using PSPSDK and let's say I buy the official dev kit. Can my game be converted (I don't know if this is the right word) to the official dev kit? What I mean is this. If I develop a game using PSPSDSK and I want to publish it commercially... Can I do it? (Getting Sony's Licen...

I noticed in version 1.4 that there is no difference in the ships movement speed with the laser on or off. Was this a fix to something that was broken in previous versions? There were no changes in v1.4 that would've affected gameplay. Can you better describe what you're seeing (game mode, level, s...

About the EBOOT laoder and C++ global constructors...
So, we figured out that rRootage was crashing on 2.0 systems because _init() wasn't being called by the EBOOT loader. To recap, _init() is the function that goes through and executes the constructors used in C++ static classes and C functions using GCC's "constructor" attribute. rRootage u...

Wouldn't it be better to politely ask Fanjita if he could add a fix to the loader? :) It would be if it were something that he could easily fix. I've already discussed this with Fanjita and he's mentioned a way to detect the EBOOT loader. The way I'm fixing it is more reliable and straightforward t...

Yeah, it's a bit disappointing that there's no precise way to pin this down. About the kernel flags, all apps linked against libSDL_main.a will show up as kernel apps, but they don't use anything that the EBOOT loader doesn't already patch out. Other people have tested SDL-based apps using OpenGL an...

There's no way it should be crashing within the logging function, because calls to the logging function use atomic writes to log.txt - the file is closed at the end of each call. This suggests that the bigger problem could be coming from the EBOOT loader. It's already been shown that the EBOOT loade...

build (66): enter init (27): Thanks for testing. The log looks a bit strange - did you allow rRootage to completely crash or wait for the memory stick LED to stop flashing for at least a minute or two before grabbing the log? If not, could you please run it again and post the log? Thanks. And I can...

What line is causing the crash out of interest? If there's anything you'd like tried with the code or test binary i'm sure they'd be many people that would oblige (including myself). The crash occurs during the call to BulletMLParserTinyXML::build() made on line 44 of barragemanager.cc. It crashes ...

If you want bitfield extraction and insertion, check out ext and ins. The syntax for ext and ins are: ext rt, rs, pos, size // Extract size bits from position pos in rs and store in rt ins rt, rs, pos, size // Insert size bits starting from the LSB of rs into rt starting at position pos The opcode t...

The ALLEGREX CPU supports MIPS rotr and rotrv. GCC does a pretty good job of detecting a rotate, if you have code like this:
the compiler will convert that to to the appropiate rotr instruction.
Code: Select all
val = (val >> shift) | (val << 32 - shift)
