VTxx Dumping Thread

[davidstech]

Thanks for the source code, I'll look at adding that to MAME - at the moment the sound support is still very limited for all VTxx platforms so there'll be some preparatory work needed first I think. Unfortunately no sequence of buttons seems to get into that tune.

MAME APK will hopefully be done soon.

can someone seperate the 220 in 1 dreamgear or not?

[davidstech]

Yes, it's possible, but a number of the most interesting games wouldn't run in anything other than NRS-Nintendulator or MAME because they use scrambled opcodes

no NO NO NO NO, you dont have to do this  >_>

Unfortunately I think the MAME on Android thing is a bit of a red herring, as it stands its UI is basically the MAME PC UI with no touchscreen support. I think this will only be useful if you have a bluetooth/hardware keyboard, or possibly bluetooth joystick.

APK download anyway (64-bit only) : http://davidstech.net/games/mame_vtxx_aarch64.apk

I haven't been able to test this at all as a result.

While I'm at it, here is a pack of VTxx games for MAME:  http://davidstech.net/games/multis/MAME%20VTxx%20Pack%202018-02-04.7z

I have a GPD XD, david, which is a gamer's Android device. I'll test it out and let you know.

[davidstech]

That will need a 32-bit build IIRC, which I need to make.

[Y2K05]

How easy is it to make a 32-bit build? And yeah, I wondered what type of architecture it would need.

Isn't it possible to make a MAME build solely for a given system? I think I did that on Linux before.

[davidstech]

Yes, it is, I've done that too. Don't know why I didn't realise. Won't take long then (it's not hard just a full build takes a while).

[davidstech]

If you're on Windows, NRS-Nintendulator is probably a better bet. Otherwise MAME 0.194 has everything before the DGUN-2573 and FC/Family Pocket already. I can make a build, but I'm not keen on the idea of maintaining many private builds of MAME.

As far as I know, MAME does not support Famiclones with mangled banking register addresses such as Samuri 60-in-1 or Z-Dog.

Thanks for the info though, that shouldn't be too hard to implement. VRT do like their mangling, what with mangled banking registers on the VT03, bit swapped opcodes on the VT168 and now XORed on the latest VTxx.Multi arch APK (32-bit ARM and 64-bit AArch64) : http://davidstech.net/games/mame_vtxx_multi.apk

This has the full MAME for AArch64 and nes_vt (the VTxx driver) only for 32-bit ARM.

A few other comments regarding MAME:

• mc_dcat8a does not like more than 2 KiB of internal RAM. Mighty Bomb Jack will act strange with more.
  
• $4105 is not emulated yet as an exact mirror of $8000, causing Mighty Bomb Jack in mc_dcat8a and Violent to look garbled. Note that EmuVT makes the same mistake, while FCEUX does not.
  
• Consider using my attached VT03 palette generation algorithm, which I have matched to get as close as possible to EmuVT's hard-coded palette
