However, what do you plan to bring more than mGBA for example?
Good luck! BTW, do you have plans to edit the DualGB mode so that it can use GBHawk? Or maybe even make it support more than 2 games at the same time?
I would once again ask: This exact thing works at speedrun.com. Why wouldn't it work here? There, many games have many categories that have technically speaking "arbitrary" rules and limitations, but these have been decided and agreed by the speedrunners themselves. The list of limitations in some categories for some games can be quite extensive (and sometimes not without slight controversies). But nevertheless, it works there, and can result in very popular speedrunning categories (once again Ocarina of Time being the posterboy for this, although it's of course not the only example.)
However, there's still another issue. Basically, the game's audio is out of sync. Characters' mouth movements don't sync with their voices. This also happens in mednafen, no matter the dumped image. I once created an account in their forum to report the bug, here's the link: https://forum.fobby.net/index.php?t=msg&th=1571&start=0& According to the last post, this apparently has to do with CD-ROM seek time not being properly emulated. This could prove useful if you're willing to look into fixing stuff.
Console-verified using Game Boy Interface.
I was playing Holy Diver just now, and I got softlocked after the fifth boss. Normally, after the boss dies, the end of level music begins playing and the floor opens up beneath the guy on the cross and you jump down after him. However, in my situation, the music never starts up; the floor doesn't open, and I'm left trapped in the room. I've retried the fight a few more times, but I always get the same result. I'm using v2.2.2(64x), playing the game with the QuickNes core.
Despite showing up and showing the domain when in action, the code data logger doesn't appear to work with NESHawk. Is this a bug or was it just not fully implemented? Seems like it should be working with NESHawk of all cores. It only shows the "RAM" domain and despite causing the game to lag up (it's clearly doing something) it's not populating that domain.
Ok we can now tilt 'n tumble!
I think I got everything working with the mapper and EEPROM. Motion controls and centering work, saving works, and TASing is possible.
However, I've never had a GBC or played this game, so I don't really know if the controls feel right, or if it gives the proper playing experience. So, if you are interested in this game I would really appreciate some testing and feedback. (I know there are a few graphical bugs, I'll work those out over time, I'm primarily interested in how it controls.)
Some notes on controls:
You control the angle of tilt directly with the controls. This means there are some nonlinear effects. They aren't really that noticable in casual play though, since the angles are not that large.
The control scheme is based around rotating about the up-down tilt access first, then rotating around the left-right tilt second. However, both rotations are around body fixed axes. This means that left-right tilt is coupled to the up-down tilt. The effect of this is that left-right tilt is less effective as up-down tilt increases. This might be an important consideration for a TAS, but so far in casual play I didn't see any serious impact.
The current control scheme assumes you tilt slowly (basically the only accelerations on the system are from gravity.) There are no induced accelerations from fast motions. This is one area where there might be noticable differences between real play and emulator. I can simulate them if the feedback is that it's really needed.
I have absolutely zero experience in emulator development so even if I did make it work, it probably wouldn't be pretty. I may take a look though assuming I can find some good references. I have a metric ton of C64 games in T64 format rather than TAP.
On another note, does C64Hawk support the T64 format? It's not part of the filter when loading roms, but the core recognizes T64 files as valid files. I can't get it to run any games so I'm guessing it doesn't work? When loading a T64 file, the C64 RAM is populated, but RUN doesn't launch the game. Edit: Looking at the code it looks like the framework is there for T64 files but it doesn't actually know how to handle them. Any plans to support T64 in the future?
Sameboy runs the SGB at the SGB1 clock speed, whereas BSNES runs the SGB at the original clock speed. Is BSNES emulating the SGB2?
I've made some more commits to GBC, and finally fixed the long open bug with Sachen Beast Fighter. It turns out the GBC Warriors of Might and Magic was doing the same thing as Beast Fighter, so it was pretty easy to work out what the intended behaviour was.
Thanks for the hard work! Are you gonna implement a hacky support for the GBA mode, or are you gonna wait for the actual bios dump?
Over the past few days I've been expanding GBHawk to have GBC support. It's now in a fairly presentable state so I thought I'd make an announcement in case people want to try it out. It's still a bit buggy but I'm hoping to iron things out over the next couple days. All of the grunt work of sorting things out between GB and GBC is done though, and all of the basic GBC functions are in there (except IR port.)
Originally I was going to hold off on doing this until some new test ROMs became available to properly fix PinBall Fantasies, but I don't see them yet and I wanted to get started on GBC while I have a little time to focus.
GB is still the primary accuracy component of the core, but I'll be working on GBC accuracy as the core becomes more mature.
In terms of performance for me it currently runs about 130 fps, while the GB side runs around 210. I think 130 isn't too bad considering double speed mode, HDMA, and colorizing things makes the core do considerably more work. Maybe some optimizations here and there can improve things a little more, but Gambatte is still 10x faster anyway.

http://hhug.me/gbx/1.0 Someone is is making a new file format for Game Boy games. I don't know if it's a good idea if GBHawk could support it.
This is the reason why I wonder, since M.A.M.E is "soon" being integrated, this emulator and this one have not been tested for integration since the "waterbox" exists for BizHawk. And WinUAE seems perfectly suited for such integration, but nothing seems to be planned. We need a CPC emulator as I mentioned earlier, and a Game & Watch emulator, and that would be almost perfect!
