Re: DSP Rom? - 14 years ago
Bump I've been curious about that too, while recently looking into the ASND library (Hermes indeed developped his own DSP microcode using Duddie's tools, to perform something similar to what the official one is doing). According to what I've read, the officiel DSP microcode can do some additional things that might indeed be useful in some projects (emulators for example, toby ekeeke - Hardware
Re: sega genplus, play 32x games in emulation - 14 years ago
Nope, Gens has 32x and Sega CD support and is indeed open-source. However, these parts are written in x86 asm and therefore would need to be rewritten in C or PPC asm, which, also considering the modifications required to integrate that in genesis plus, would be the same as rewriting a whole 32x/SegaCD emulator from scratch. Also, considering the requirements for 32x emulation on computer (theby ekeeke - Homebrew Applications

Re: No output on Composite / RGB Pal Wii - 14 years ago
QuoteI did some more testing on the composite signal and found out that even on a working wii I cannot measure any signal on this pin. composite pin is typically carrying video / sync signal, voltage level is varying in time, you would need an oscilloscope to measure it more precisely QuoteThe RGB signals are giving me some voltages fluctuating from 200mV to 1.8V... this means the video encoby ekeeke - FixMii
Re: No output on Composite / RGB Pal Wii - 14 years ago
I got similar problem for a year, no more RGB (never tried component), only composite (even through the RGB cable) I measured RGB switch signal and was 0V as well, composite sync is ok, did not test R,G,B signals In your case, it seems it's the composite sync which is affected, it is used as synchronization signal by the TV in RGB mode I tried opening the case and checking connections wby ekeeke - FixMii
Re: Genesis Plus GX won't display video! - 14 years ago

Re: Some help with GX settings - 14 years ago
QuoteLegacyCrono GX_SetCopyFilter(rmode->aa,rmode->sample_pattern,GX_TRUE,rmode->vfilter); I believe that this changes how the video do the copy from buffer to screen according to your TV mode (NTSC, PAL, etc).

Re: Access to Registers - 14 years ago
QuoteThis brings up the question, however: does homebrew have 100% of the Wii's "attention"? Like, if one were running the program on Windows, it's also running a bunch of stuff in the background, which makes straight "time" measurements inconsistent and unreliable. However, if the homebrew had the full capacity of the Wii (I believe this is called running it in Kernel mode?) then it woby ekeeke - Coding
Re: Unable to Load State on Genesis Plus - 14 years ago
Are you sure you loaded a ROM first before trying to load a savestate ? Also, check that there is a .gpz file with the same name as the ROM file in the /genplus/saves directory on your SDCARD, otherwise this means you didn't saved anything. You initially said you got a black screen when loading savestate, now that it does nothing, if you want help, you need to be more clear ...by ekeeke - Homebrew Applications
Re: Unable to Load State on Genesis Plus - 14 years ago
what you mean by "when i select it" ? There is actually no way to select which savestate will be loaded... The fact you get a black screen and are still able to go back to main menu make me wonder: you didn't tried to load a savestate file from the "load game" menu, don't you ? Because this will not work, proper usage is: 1/ load a ROM file (Main Menu -> Load New Game)by ekeeke - Homebrew Applications
Re: Requesting a 32X Emulator for Wii. - 14 years ago
yeah, I know about the confusion people sometime make, I was just trying to clear up things for once ^^ Genesis Plus is the original name of the emulator : The Wii/GCN port is named Genesis Plus GX, GX being a reference to the graphic accelerator hardware used in those consoles ..

Re: does genplus support 2 players? - 15 years ago

Re: Idea for Wii N64 - 15 years ago
yes they are, this is why this is called dynamic recompiling what you are proposing is similar to another technique called static recompilation (however, you can not just compile a ROM into a powerPC executable, it's not so simple and emulators just don't work like that) from what I know, there are two common downsides to static recompilation: - it's hard to differentiate databy ekeeke - Homebrew Applications
