SameBoy recommendation??[edit]

SameBoy is becoming very accurate lately and has a great libretro core to boot. Should we recommend it? - Syboxez

I don't know the answer to this but just wanted to stop by and say thank you for asking as opposed to just changing it. I wish more people would do that. We'll see how this one goes! Karasuhebi (talk) 20:14, 1 March 2018 (EST)
I might run some accuracy tests myself and change it if it is on par with Gambatte if nobody responds in a week. --Syboxez (talk) 21:41, 1 March 2018 (EST)

Just ran blargg's GB tests on SameBoy using real bootroms (same results with the included open source bootroms) and my results are:


cgb_sound = 100%

cpu_intrs = 100%


CGB = fails 08,09,10,11,12 (fails on real CGB and AGB hardware as well)

DMG = fails 01

instr_timing = 100%

interrupt_time = 100%

mem_timing = 100%

mem_timing-2 = 100%

OAM_bug = Failed Causes, Scanline timing, Timing bug, Timing effect, and Instr Effect, passes everything else (Same results on real CGB and AGB hardware, but everything passes on real DMG hardware, unlike any emulator, even in DMG mode)

halt_bug = 100%

Compared to existing emulators:

Barring the DMG_Sound tests, SameBoy is on par with Gambatte and BGB accuracy-wise. Also SameBoy is active and open source, unlike Gambatte (activity-wise) and BGB (source code). I think we should recommend it. --Syboxez (talk) 12:42, 4 March 2018 (EST)

Yeah I don't see a problem with recommending it, but let's see what other people say. Karasuhebi (talk) 14:31, 4 March 2018 (EST)
Have no issues with the recommendation, but I just want to point out that it doesn't have an entry in the comparisons. I find the recommendation should at least be backed by an explanation as to why it's recommended aside from these test results. How does it perform? Is the standalone UI any good? That sort of thing. FosterHaven (talk) 14:55, 4 March 2018 (EST)
The reason there is no entry in the TASVideos link is because the emulator didn't exist as of the time of the testing. I think the UI is perfectly fine, but is completely keyboard-based. Not many options to worry about. There is also a libretro core if you don't like the UI. The testing done here was my own personal testing and the tests are the same ones that TASVideos used. Feel free to replicate these results with the test ROMs (link in the TASVideos page). I have seen no performance or input lag issues with this emulator. As for a comparisons entry, that would have to be added. I may do that when I have time if someone else doesn't beat me to it. --Syboxez (talk) 17:01, 4 March 2018 (EST)

I'm just copying over TASVideo's page right now, but I just wanted to ask... you say specific revisions of real hardware fails certain tests (CGB and AGB?). Should that be in the table as well? I ask because the amount at the top that's graded 100% should say original hardware (the PS1 Tests page says PlayStation). FosterHaven (talk) 17:27, 4 March 2018 (EST)

I think that's a good idea. The 100% number comes from real DMG hardware, and that's what all the tests are measured against. When compared to real CGB and AGB hardware, Gambatte, BGB, and SameBoy are all 100% accurate according to blargg's tests. I also think we should add other tests as well (Gambatte and Mooneye specifically) with real bootroms (Mooneye specifically fails when not using real bootroms). Also for clarification, CGB and AGB = Game Boy Color and Game Boy Advance. DMG = OG Game Boy. I also only ran the DMG_Sound and OAM tests on real hardware, so if you have a flashcart, testing everything would be a good idea. DMG_Sound combined test gives a black screen on emulators and on CGB/AGB, so those tests need to be run individually. I'll be happy to run all tests on real hardware, but my flash cart is a PITA (EMS 64M USB), so I won't be able to do it today. --Syboxez (talk) 17:30, 4 March 2018 (EST)
Thanks for clarifying the models, I didn't think AGB meant the Game Boy Advance but in hindsight it should have been obvious. I'll add the revisions but comment them out until you can get results. They're not needed immediately because I'm still trying to add the other tables. Feel free to add the results in now or whenever you can. FosterHaven (talk) 17:52, 4 March 2018 (EST)

MeBoy recommendation[edit]

I would add it to the page myself, but I figured it would be better to ask before doing anything.

MeBoy is an emulator -the only emulator, I think- built for J2ME cellphones. This includes most of Nokia, Sony Ericson, Blackberry and lots of others between 2004 and 2008.

It's not active anymore and it has a lot of problems, but it's a working emulator that can run most Gameboy and Gameboy Color games well enough. If you own any of those phones, you have a cool console to carry with you.

I've gotten to love this project, it's the first emulator I ever used and the one I finished most GBC games with. No other J2ME emulator is in this page, and I think this one would make a good entry, if only a honorary mention.
