Re: Libbet and the Magic Floor

Yeah, the flicker is noticeable on SGB, and can be quite jarring under most palettes (including the default) as it changes the hue as well, not just the luminance

Re: Super Game Boy system extensions

Well I'm not talking about running the game exclusively on the SNES, like Space Invaders does. I mean to run a program while still running a (nearly) typical game boy game. So the game Boy could be running its normal program (sans sprites), the SGB is is displaying the GB screen and its other effec...

Re: What is a good gameboy emulator

I'd like to add that a GTK front-end is being worked on for SameBoy, which would port the Cocoa-exclusive (= macOS-exclusive) features to Linux and possibly Windows as well.

Oh, yeah, I forgot it could scroll. If so, then I guess this is the least awkward-looking way.

Re: 144p Test Suite (was: STN torture test)

That attribute clash on the Green Hill test looks so "SGB"... I guess the reason why it's so noticeable, though, is because you're only encoding horizontal strips?

Re: STAT bug vs STAT IRQ blocking

There is a last thing to note in regards to STAT IRQ blocking: the LYC coincidence interrupt appears to be delayed by 1 cycle after Mode 2, so it does not block if Mode 0 is enabled as well. (This also means it's delayed by 1 cycle, obviously.)

Re: Nintendo files a Gameboy emulation patent

That sounds a lot like per-game hacks? That said, the 3DS VC emulator has some of those, for example Pokémon's emulator-enabled trading screen.

Re: Odd SPC music loading in the SGB game Beach Volleyball

I have updated my WIP disassembly with the relevant functions, which are here . The `WaitFramebufferFilled` function is wrapped in interrupt-disabling code, I wonder if this is the case on SGB1v0 as well. (SGB1v2's sole modification from SGB1v1 is applying the OBJ_TRN patch at boot-up, so Nintendo d...

Re: Odd SPC music loading in the SGB game Beach Volleyball

The mystery deepens. In the SGB1v1 and SGB1v2 BIOSes, the function at 80:C573 is... `ProcessSOU_TRN`. Here is a slice of the SGB1v2 disassembly I'm making (note that SGB1v1 and SGB1v2 are almost identical, and most importantly aren't shifted) .importzp FramebufferFarPtr ; $0098 .import PtrToFramebuf...

Re: Using SGB as a makeshift SNES flashcart

My GB code is uttely bad, for a fairly unique but stupid reason: at some point the SD card I was using to feed my flashcart GB ROMs ceased working, so I kept running the same (at the time broken) ROM. SO I ended up fixing problems and things that weren't (to my great confusion). Since I wasn't plann...

Re: Using SGB as a makeshift SNES flashcart

That's because nothing has been published; the disassembly IDB and my (admittedly pretty botched) GB+SNES code are both sitting on my computer. Do you want me to upload those?

Re: Using SGB as a makeshift SNES flashcart

School and other obligations meant I haven't had time so far to progress my SGB firmware disasm or work further on this. It's still a thing I want to do, but there are also a lot of those; that said, I'm not the only one interested, so maybe someone else can pick up my efforts.

Re: "return flase" causes PHP website to be hacked

if a programming language has syntax that is commonly but silently screwed up, it becomes the fault of the language author and not the programmer. Yeah, but one could also blame the programmers and companies that are using that language. It's hard to blame someone for using a language when there's ...
