Not sure if it's the same with a real controller but with an emulated controller in gamekeyboard.

Xbox LB = DC Start
DC LT and RT not mapped.

It freezes while loading. Register related IIRC.

Update. It's TMU->Reg_TCNT.

The aforementioned game crashes after the menus, before going ingame.
It only happens when the ARM dynarec is used.

Interpreter works
x86 dynarec works

this was SMC

Some games abuse PowerVR. Examples:

Mars Matrix
Power Drift (from Yu Suzuki Gameworks)

We gotta handle those cases at some point.

A lot of ingame textures are messed up and drawn as plain purple. Tested with the PAL version on Note3.

Bump Mapping is not handled currently.

Some games that use it:
Rayman 2 uses it a lot.
Shenmue 2 only a bit.
Quake III?

The Google Play Store don't allow me the download, because the device hardware is recognized as not compatible.

Device: Mad Catz M.O.J.O. - Android TV Gameconsole

Emulator crashes upon bios or game boot. Issue may be caused by an OpenGl failing to initialize. A copy of the log can be found here : https://www.mediafire.com/?713zln3bp0cp20k

@rtissera has made an updated lib from the old chd code that supports v5. We should switch to it - https://github.com/rtissera/libchdr

"Stable" releases

• Google Play store

Nightlies

• Snap edge channel
• builds.reicast.com (CI, win86/win64/android dev builds)

Considering

• Ubuntu ppa
• Packages: deb, archlinux
• Packages: freebsd

(was: publish to 3rd party stores)
We should have a presence to all android stores. @MrPsyMan, can you take a look at it? Some stores have already "imported" our apk from the google store, but others not yet. Also, that chinese list again pls :)

It happens on different games, for different reasons.

Examples of some games affected:

Bangai-o
Idol Janshi
King of Fighters 99
Twinkle Star Sprites

From personal experience, I assume that fixing Idol Janshi will fix most cases where anti-aliasing and the likes take place, whereas fixing Bangai-O will also take care of the rest cases where 240p output is used.

Just some wishful thinking.

GD-ROM error handling through SCSI sense codes is used for disc swapping by some games.

Only one commercial game requires this:

D2

The particular game does not let you save before changing discs. So you can't progress.

Saving between discs is possible on every other known case. So nothing else requires this function.

Good thing that we currently do not offer a disc swap option... at all. :p

Affected devices: Xperia Play (versions?)

Platform: Android 2.3 w/ snapdragon S2

(We don't have a device to further study the issue)

This is unlikely to be solved soonish, as it is a limitation of the OS

Dear reicast team,
Can you add menu for customize on screen controller? So we can move analog pad to the bottom left corner screen.

Hi,

I'm using an APK built from the last github sources on a Xperia Z 4.2.1, French Sony Rom.

When I launch a game there is no problem, but if I exit this game and try to launch another on, the phone vibrate as usual and then I'm back on the phone home.

The app does not seem to be closed, if then I go back in the app and try to launch a game again, this time it works.

If close the launched game this behaviour re-appear.

Bye,

Processeur.

It's a funky color scheme.

Flat polys use 1 vertex for color. That's what dknute once told me. For some reason I never looked at it.
Apparently, we treat them the same as gouraud polys.

@lioncash, @neko68k looks like the fragments based code is brokenish. I worked around the crash locally, but couldn't get it to work (plus, some icons are missing anyway).

The crash issue is that fragment_container is missing from mainuilayout_fragment.xml, and even if I add a placeholder frame layout it still doesn't work. There are some complaints about getActionBar() as well (no idea if they lead to a crash, maby later on).

Any ideas ? :) I spend all my day debugging that shenmue (#62), but I can work on it tommorow !

We currently have a litlt bit over 500 active 2.3 users, so this is a blocker for r6.

Metropolis Street Racer is completely playable however...

• non-CD audio doesn't play (engine noise, button press confirmation, etc.)
• In game demos (go to "Options", "Demos") graphics are hugely glitched. Doesn't really matter, but may as well report it whilst I'm reporting the audio.

I recall Guilty Gear X having sound volume issues when switching between the stereo and mono output options on the ingame sound test.

Unfortunately both of my DCs are broken, and even if they weren't I only have mono sound cables, so verification on my end is not possible at the moment.

Some users report that they are unable to map the emulated analog triggers to digital buttons on their controllers when using "touch button->controller button" mapping software.

It's also next to impossible to support multiple key presses simultaneously for games that require them.

What do we do for these cases?

Depends on #26

For some reason, shenmue is broken with it (bad graphics). Disabled for now. This is a messy part of the dynarec/jit compiler, and it would be great if some brave soul could dig into it!

SH4 has support for full memory remapping, and this is currently not implemented in reicast. nullDC included some parts of it, but the support was mostly buggy and was never supported for the JIT. From my knowledge, only Makaron handles this.

Windows CE based games, Bleemcast, Linux for Dreamcast and NetBSD for Dreamcast use the mmu to its full potential. Examples: Virtua Cop 2. Complete list at https://segaretro.org/Windows_CE

Some Katana-SDK games use a subset of SQ remapping, which is implemented. Examples: Ikaruga

I imported most of the mmu code from nullDC to this project in #818 and d99c803, however, I have really tested it.

Getting mmu working is a /very/ complicated task, and integrating it in the JITs will take major work the ugliest & most complicated areas of reicast.

We need a brave contributor to look further into this :)

Again some wishful thinking.

MMU is not supported currently. This has to change.

Gauntlet Legends has serious graphics issues of all kinds when using the ARM dynarec.
Polygons are missing, textures are corrupted, most of the screen is black.

The game works fine on interpreter and the x86 Dynarec.

PS: The game currently does not boot due to a known regression, but that is a different issue.

this was SMC

import android.view.InputDevice Only exist API9 (Android 2.3) and higher .

I have been searching for one and there only seems to be the pandora one here: http://pandorawiki.org/Reicast_Compatibility_List.

Could one go on the project wiki here on github?

Please tag as documentation.

Depends on #26, and we also need UI

Hi guys, you are doing a really great work with this here. I'd like to ask you if you are able to make the Xperia Play work with it's controls using this amazing emulator, because I hope it will be stable one of these days.. I think you too, if it's not a problem for you, could you please do it for the Xperia Play community? We love having classic emulators.

Thanks in advance.

Cheers.

Targeting gcw zero & related h/w

Requires rooted device. I also don't have a mac or iphone, but i'll probably be able to have access for porting usage at some point. Also, gb_away is working at it

lt r buttons not work in android version in code veronica

The current x86 backend is more of a validating backend that something that can be used to run things fast. This needs to be addressed.

We also need linux/macosx/etc support on the jit

Please fix the shenmue crash at the beginning, tried 3 different devices, same prob.

I'm requestin this as there's a guy by them name of cyclonmaster who compiled the latest source code/apk (of course I tested it) Seems the graphics are now OK(thx btw), but unplayable due to force close of the app, just after you walk outside. thx

If your aware of the then ignore this, this was just fyi.

Sonic Adventures 2 - Missing Polygons

Sonic Adventures 2 is missing some texture, but they reapears depending on the vision angle it seems.

(Using Pandora build)

The structure in renderer_if.cpp don't like Renderer* 'rend' but if change syscalls to with _ rend or rend_ it's compile fine

maybe bug in the compiler visual studios 2013??

Tested on our Galaxy tab 7.0 Plus. Other devices might also be affected.

PowerVR comes to mind first, having mip-mapping enabled results in garbage textures.

Other hardware might also be affected.

Auto detection of the hardware and self-configuration will fix that.

Debugging on Android is almost impossible right now. The google tooling is very minimal, and debugging the JIT is pretty much differential debugging and guesswork. On the linux side of things, it is slightly better (at least gdb works reliably, but very slowly on asm view).

This is a combination of the project being big and complex, of us not having internal debug tools, and of the android platform being over complicated and not that well supported.

Short term solutions

• Debug on linux/arm hardware for JIT bugs (pandora, cubix, pandaboard)
• Cross test on windows (it seems we do have some arm only jit bugs though)
• Coordinate with more people so they do manual testing work

Missing tooling

• SH4/ARM/Dreamcast level debugging (drk has some plans for it, but it'll take a while)
• OpenGL ES Debugger (NVidia tools on the Shield should help with that)
• Profiler (nixprof/reprof need to be worked on, also NVidia profiler + oprofile on linux/arm)
• JIT Inspector & etc (gdb is simply not up to the task, custom tooling required. Perhaps we can re-use something?)

Other issues

• android builds are really, really, really slow
• we don't have automated tests. Investigate feasibility (lxdream has some)
  ** Perhaps look for arm hardware to run arm jit tests on ?

A recent example is the Shenmue crashbug (#62), which even after spending a LOT of time debugging still remains a mystery, and only appears on armrec (even with minrec config).

Any suggestions to make the situation better are welcome.

Noticed on a few games the textures are tiling with gaps between them on menu screens, here's a pic of Crazy Taxi with tiling around the logo.

Currently we use stale textures, which leads to issues in some games (mvsc2, sf3ts, possibly others)

mvsc2

sft3ts

I detected on shenmue one and shenmue II needed implemented Opcode : 0 : 359CD51B Fatal error : inimp reached sh4 cpu.

On Shenmue 2 graphics look amazing

but crashes on loading times Opcode error.
