Work in Progress: new VT168 emulator

[davidstech]

No it's not MAME based at the moment. Would be a possibility for the future though Some good news. Most of the critical PPU bugs have been fixed, and I've made an initial attempt at implementing the MiWi 2 input (it works but it's quite hacky and the button order isn't correct ATM).

It does now seem to run all of the games I tried without crashing and with some degree of graphics visible, most of the games do still have some PPU issues - mostly due to a bad scrolling implementation.

Hopefully it won't be too long to fix these remaining issues. Now approximately 90% of the graphical issues are solved. The only games with major issues are the "3D" racing games, I suspect it's due to whatever they use for perspective. Still a bit of work before it's ready to be released, in particular some kind of initial UI and a Windows build. Public release of version 0.10 posted at the top.

I don't think there's ever going to be one for the GBA, buy a GPD Win[/quote]ok, if it doesn,t work on gba, can the vt168 emulation maybe work on a nokia n gage, or a nintendo ds  :|

From a technical point of view it might work, anything that can emulate a SNES could emulate a VT168, the problem is it would be an awful amount of work which I don't think anyone is going to do given the small number of people interested in such a thing. At the moment I haven't spent any time optimising it so it only just manages 50-60fps on a high-end desktop.

Do you think emulation on a handheld like Android or Nintendo 3DS is more likely? Just wondering. It would be cool if it were on 3DS or Android since people still use those handhelds. Not just VTxxx but the VT03 and VT09 stuff too. I've been enjoying VT02 games on VirtuaNES on 3DS, and NESemu on my GPD XD.

Just wondering is all.

It turns out the reason that the racing games had graphical problems is that they were changing the PPU setup and tile map mid frame, which I hadn't anticipated in my code as I underestimated Waixing...

A new binary release with this fixed will come soon, just need to sort out a couple of other issues too.

Screenshots of some of the games are on the VTxxx page on BGW.
