I can also confirm that there are serious graphical issues on a real MVS. On a postive note, I really like the intro ;-)

You are an absolute legend! I can confirm that in
beta-v0.5.3 the sound and the music are working like a charm. I am also happy to report that the menu hot key feature is also working again too :-)
As for the graphic glitch that I mentioned, you can see it in the top half of the screen when the character goes into the first door:

Sorry about the video quality; I have to hold my phone with one hand and play with the other to record. I hope this helps!
Hi,
I am super happy to report that the music drop-out issue really has been fixed in the new version of Bubble Bobble; Thank you very much for fixing that!
To help you figure out what is going on in Street Smart, I have uploaded the following short video of the sound issue:

There does seem to be some music in the very background, but something seems to be "looping" over and over. I hope this helps!
I don't believe that it has anything to do with my BackBit Platinum cartridge. The music in almost all your other conversions works just fine... that is, except for Bubble Bobble, where it stops in the middle of the first level. I must also point out that the sound and music work just fine with all official Neo Geo releases too, so that also doesn't speak for my cartridge having an issue.
So I have tested both now. Unfortunately, the test build did not fix the sound, but I do believe that in 0.5.0 the gameplay was smoother. I did, however, notice that the menu hot key shortcut, which works in all your other conversions, does not work in Sunset Riders. I will try and get you a video of the graphic glitches that still seem to persist in 0.5.0 tomorrow!
Hi,
I just got around to trying out beta-v0.4.7 on my MVS (UniBIOS 4.0) using my BackBit Cartridge. I am afraid that there is no sound or music at all (I haven't tried any other versions). During the game I did notice that the gameplay seems rather slow and there were some minor graphic glitches that would pop in and out rather randomly.
Hi,
I just wanted to let you know that I tested this and your "Tiger Road" port on my MVS (UniBios 4.0) with my BackBit cartridge, and both ports work really well. Congratulations on the great work!
The only issue I had when using my Backbit cartridge was that it's not possible to return to the Backbit cartridge menu using the defined key combination. I found the following information on this topic in the BackBit forum:
The platinum cart patches a vblank handler onto most titles for rebooting the system back to the cart menu when the player presses a button combination (aka Menu Hotkey, defaults to B+D+START)
It writes P1 input to a register that the cartridge intercepts every frame, does its magic on hotkey press, then warm boots the console.
move.w (BIOS_P1CURRENT ^ $6b17), $2bacb0
Would it be possible to implement this feature in both games (and any future Neo Geo conversions)? Thanks a lot in advance and keep up the good work!

It the output should work with MAME too
Hi,
I just gave your KOD (Beta16) port a quick spin of my MVS (UniBios 4) using my BackBit cartridge, and here is my initial feedback. It plays really well, and I couldn't see any graphical issues at all, but I did notice a minor issue with the music. It seems to stop in level 1 right before the character does his "scream" at the very start of the level. All sound effects played normally for the entire level, and the music then started again when the boss/main enemy showed up at the end of the level. Ironically, the music played just fine at the beginning of level two but then seemed to drop out during the boss fight. I am afraid that I didn't play much further than that, but I hope the feedback helps. I also really dig being able to change the settings before the title screen. That is a really nice touch. Keep up the good work!
Hi,
I just tested v0.2.6, and it works just fine for me. I am also happy to inform you that the graphic issue on the Psygnosis logo is fixed. The only issue I noticed is some white lines on the top of the screen when you die. That is about it.
As for my issue with SOTB and OUTRUN not booting on my BackBit cartridge, others in the forum didn't have the same issue. It really did turn out to be a mistake on my side. I am really sorry about that!
Just to clarify, the game literally stops loading a second or two after the ROMs start loading on my BackBit cart. It is as if there were an issue with the ROMs or something along those lines. After it stops loading, it shows the BackBit Bios splash screen, and then the screen just goes black. There isn't really much to see, and it is over in a few seconds, so I am not sure a video will help in this case.
Hi, I downloaded your MVS/AES build before you removed it, and I just wanted to ask what the main issues were? For me, the main issues seem to be that it was too fast and the final end boss didn't show up. Other than that, the sound and graphics all worked fine from what I could tell. I did notice that there was a minor graphical glitch in the crystal ball in inbetween each level, but that was about it. I tested it with my BackBit cartridge on my MVS with UniBios 4.0.
