Re: IOS_ReloadIOS doesn't work in binary from MEM2 - 14 years ago
Quotesorgekeeke, you can check thread in libwiikeyboard (keyboard.c).. Yes, unless I don't understand the code, this seems to be an error static u8 *_kbd_stack ATTRIBUTE_ALIGN(8); static u8 *_kbd_buf_stack ATTRIBUTE_ALIGN(8); This should not be declared as an array of pointer but an array of bytes, right ?

Re: IOS_ReloadIOS doesn't work in binary from MEM2 - 14 years ago
QuoteI saw in some places of libogc: it sets stack for some threads using static allocation inside data section of binary which looks terrible for me. Probably libogc does some similar nasty things while IOS reloading... hum, where did you see libogc doing that ? Data section is copied from the .dol by the loader and left untouched by libogc, otherwise NO application would work correctly. Theby ekeeke - Coding
Re: The advent of HBC, and how some emulators stopped working - 14 years ago
This is very simple: those emulators were released BEFORE the new HBC update, they need to be recompiled to take libogc changes in account regarding USB, the fact they are the "last stable release on Wiibrew" does not mean very much, what matters is the release date. And FYI, you could have read my comments on your issues and you would have noticed that it got "invalidated" because technicallby ekeeke - Homebrew Applications
Re: my dol loader just hangs... - 14 years ago
yes, this is the cause of the problem, your loader should be running from 0x81200000 and it isn't it must be a problem with your makefile, it should have this line: LDFLAGS = $(MACHDEP) -Wl,-Map,$(notdir $@).map -Wl,--section-start,.init=0x81200000by ekeeke - Coding

Re: my dol loader just hangs... - 14 years ago
well, I'm not really sure if using read works, in theory it should but I never tried it. again, you should really use a loop to read file in smaller data chunks; like this: /* Open file */ FILE *fp = fopen("sd:/apps/pngmove/boot.dol", "rb"); if (!fp) { printf("null dol\n"); sleep(1); return 0; } /* Read size */ fseek(fp, 0, SEEK_by ekeeke - Coding
Re: IOS_ReloadIOS doesn't work in binary from MEM2 - 14 years ago
Beware that IOS is using the upper 12-16MB of MEM2, if your code is running from there it obviously can cause issues with running IOS. Also, DOL loaders (like the HBC) uses MEM2 as data holding space so it's generally not a good idea to make the DOL you are loading use this area as well, when it will be copied in memory, it could overwrites the loader data. I guess that more details on thby ekeeke - Coding
Re: my dol loader just hangs... - 14 years ago
Have a better look on how to use the "read" function, your code actually makes no sense at all. But anyway, the best way to handle this is, as I told you, to call multiple fread on smaller data chunks, in a loop. And you are still not checking the result of "fopen" before continuing, you should REALLY do it. I don't want to be mean but honestly, I think you should first be fine with Cby ekeeke - Coding
Re: my dol loader just hangs... - 14 years ago
1/ don't allocate and don't free bufptr, just make it point in MEM2 like you are doing, this is fine 2/ don't use a fixed size when reading your .dol file, revert into using fseek + ftell, this works and this is what it is for 3/ I/O read are now unbuffered in devkitppc/libogc, this means that reading too big chunk of data with fread can fail: use the read function or make a loopby ekeeke - Coding
Re: my dol loader just hangs... - 14 years ago
Most likely, your loader is compiled to be executed from the same memory address as the dol you are trying to load, the result is that the relocate function, which copy the .dol into memory, will overwrite the currently executing code, resulting in application crash. You need to modify your makefile, adding --section-start,.init=0x81200000 to LD_FLAGS should work. You can adapt this aby ekeeke - Coding
Re: Help me with finishing a port of Hexen to the Wii - 14 years ago
One of the first thing to take care when you port some existing code is the endianness. If the information in files header (id for example) is larger than one byte , you might need to do some byte swapping first.by ekeeke - Ideas, requests

Re: Wii Update 4.3 - 14 years ago
This is how I understood the whole issue (please someone more competent correct me if i'm wrong) By default, homebrew compiled with the old libogc automatically reloads IOS36 on startup (if not found it uses IOS35, IOS34, etc..) so what the loader did before is trashed anyway, be it last HBC that reloads (or keeps) IOS61 in memory. I think that the code that has been used to reload IOS sby ekeeke - Homebrew General
Re: Genplus GX Problem - 14 years ago

Someone should remove this from Homebrew Browser, it's definitively not an official update but a mistake from one commiter: he uploaded the current SVN (unstable) version after adding SMB support and labelled as official one.

Re: exit() vs. return - 14 years ago
Regarding Wii homebrew, calling exit() is actually cleaner since it properly handles libogc exit (threads shutdown, memory freeing, return to HBC, etc). Remember there is no OS, if you just use "return", your application will hang and your only choice is to reboot the wii manually (well, I think so, never really tried). Actually, there is absolutely no advantages in using "return", you can fby ekeeke - Coding
Re: Render to texture - 14 years ago
The copy operation is not immediate, you need some synchronization to tell you when it's finished. GX_PixModeSync(); GX_Flush(); usually do the job Don't forget to also flush texture data from cache before using it since it was modified externally by the GPU DCFlushRange(renderScreen3D, 256*224*4);by ekeeke - Coding
Re: Genesis Plus GX only recognizing one controller - 14 years ago
What version are you using ? There shouldn't be any problem here if the wiimotes can be used in other emulators. If they don't, it means they are not properly synced (again, they must be synced permanently using the buttons on the Wiimotes and WIi) QuoteI tried that before, but the configuration of the first controller is disabled if I configure 2P.

Re: Genesis Plus GX only recognizing one controller - 14 years ago
you need to: (1) make sure all wiimotes are registered in the system menu using the "red sync button" (this is a requirement for all homebrew applications) (2) configure controllers in the emulator option menu (by default, if two controllers are detected, they would automatically be assigned). If you only have one wimmote+classic controller, you can also configure the emulator so player 1 uby ekeeke - Homebrew Applications

Don't you guys never read the README included with apps ? There is no "magical trick" ,setting up various emulators the "same way" or placing ROM files in multiple directories to get this working has no logical meanings.
