Much needed to avoid burnout these days.
Especially when it seems that all you're throwing at the wall is pointless. That sure deals a blow to motivation.
I picked one of the available Advanscene databases for savemem type detection, not knowing what all the available ones mean and what the differences are. Well, this one seems to be a Swiss cheese, full of errors and missing games.
If you have any ideas for a better database (like, what the fuck are the differences between all the Advanscene ones), I'd love to hear about it. Among the suggestions are that of using AKAIO's database, so I might look into that.
Also, a possibility to consider: detecting ROMs by game code rather than by CRC.
We're getting more timing renovation victims, and this time they're goddamn real. They all seem to be the same thing, missing/corrupted geometry. I don't know about all the games, but I looked into one of them (Spellbound), and it looks, well, not very good. The developers coded their own software version of GXFIFO DMA (the base idea is to transfer a fixed-size chunk of display list data every time the GXFIFO is less than half-full), which works by relying on the GXFIFO IRQ set to trigger when it's less than half-full.
However, the way this is coded expects that by the time a DMA transfer is finished, the GXFIFO will already be less than half-full, so the next chunk will be started immediately. Of course, there's a point in melonDS where that doesn't happen, causing the game to think the transfer has completed, and send a SWAP_BUFFERS command in the middle of the display list, which works as well as you'd expect.
Something's up with our timings. I hope we don't need to emulate the ARM9 caches.
And the goddamn input config dialog under Linux. I have no fucking idea why that would crash. I can't reproduce the crash. It's working just fine under my setup (Ubuntu 16.04). I can't even tell if we're just hitting some obscure GTK bug.
and merry Christmas to you reader.
