Single Pak Link Broken

[wildgoosespeeder]

In mGBA 0.5.0, any game that supports single pak links is broken during transmission. Tried it with SMA4 and the F-Zero games. Multi pak links are fine.

• Windows 8.1 Pro 64-bit
• Intel Core i5-3210M @ 2.5 Ghz
• 12GB RAM

To allow for single pak mode, you need the GBA BIOS enabled. When the animation is playing, press start+select.

Known issue. It's a problem with Normal SIO mode (i.e., it's not implemented at the moment).

[wildgoosespeeder]

Enhancement? Isn't this a bug?

[endrift]

It's an unimplemented feature.

[wildgoosespeeder]

But it attempts to run but fails. Seems like a bug to me.

[endrift]

The reason it fails is because the hardware transmission mode it uses isn't implemented. That's not a bug, it's an unimplemented feature.

Do you have any idea how to write it? NO$GBA emulates properly. If it is open source, you can use that, if you don't know how.

[endrift]

I had a half-working implementation previously, but I removed it due to it not working fully and breaking some other stuff. I'll put it back and get it working fully later.

Also NO$GBA is not open source, and please don't doubt whether or not I can implement a feature. I wrote the whole emulator basically by myself.

[wildgoosespeeder]

I wasn't doubting you. Thought I could save you some time, if at all possible. Turns out I can't because NO$GBA is not open source (bummer).

Ah, sorry, it came off a bit harsher than you'd meant it then. There's documentation out there of how it works, but for some reason it would bail out after transferring about 1/4 of the data, and I never got around to debugging it. It was a low priority for me due to the fact that single pak isn't really as useful in emulators as it is on hardware.
