www.youtube.com/watch?v=gDzm... IREM's Beyond Kung-Fu prototype (the true sequel to Kung-Fu Master) now has working backgrounds in MAME thanks to some work from Andrea Bogazzi, with me working on some tidy-ups of the code. Might still be missing a few things, but it's playable now.

I hear you all like emulation that runs at 2-5% speed. (emulating an 800Mhz ARM in software, without a recompiler....)

Jordi Tuells and Jordi Beltran (JJARCADE) dumped another one of the Dinamic / Inder prototypes. This time "After The War" which is an arcade port of the first part of the game (it teases Part 2 at the end, but doesn't have it implemented) www.youtube.com/watch?v=QuBx...

www.youtube.com/watch?v=-jqp... Andrea Bogazzi got F-1 Super Blast (from Jaleco) running properly in MAME. This is an extended MegaSystem32 board, with extra video layers and a maths DSP. AI tools were used to reverse engineer the instruction set for the DSP, which is really impressive.

an anonymous contributor also did some work on the Baiyi Animation C2 Color console. This was another Chinese system. The cartridges contain different episodes of the same game, and the final one was apparently never released. Not playable yet, but previously it showed nothing.

2 more VT09 based multi-game handhelds were dumped, one from Logic 3, and the other from an unknown manufacturer. Nothing you haven't seen before in terms of the games, but 2 new boot screens at least.

www.youtube.com/watch?v=1-WA... video of the N-Vision Monster Garage game, fully playable in MAME. Not a great deal of fun as it's just about guessing the correct parts for each track type, and if you fail to do so, you can't transform to move quickly through the hazard parts.

Back in MAME 0.286 a clone 'Mario Bros. (Japan, older)' was added to MAME. I'm surprised more people aren't talking about that. Title screen shows Nintendo Co. Ltd How To Play screen is differently Mario continues moving in the direction you press with a single tap

2191

David 'MameHaze' Haywood @mamehaze.bsky.social · 23/07/2026

Got a 'Monster Garage' plug and play. Sean did have one of these before but was unable to dump it, however Team Europe had success with the Power Rangers Dino Thunder which is almost certainly the same hardware type (even the MUSIC ON/OFF screen looks the same) so will ship this one to them.

052

David 'MameHaze' Haywood @mamehaze.bsky.social · 20/07/2026

The 'Video Challenger PL-1000' from Pelican Accessories is another early XaviX based Plug and Play we were previously unaware of. Released in 1999 this is another that doesn't have a XaviX boot logo or SSD copyright displayed. Working on the emulation of it.

2194

David 'MameHaze' Haywood @mamehaze.bsky.social · 24/06/2026

Lexibook 'Plasma Console' was dumped. Just your standard VT09 handheld device with a standard selection of JungleSoft games, but documenting that is still important.

071

David 'MameHaze' Haywood @mamehaze.bsky.social · 22/06/2026

The 'Poker & More' handheld game was dumped. Just a standard selection of JungleTac / Junglesoft games, but in a casino themed unit. Interesting choice given how they're some of the least popular games in these already unpopular units.

0184

David 'MameHaze' Haywood @mamehaze.bsky.social · 20/06/2026

The TV part of a Lexibook LG10 (or IG10?) was dumped. It's a similar 6502 based Elan as the TV Board Games units. There was speculation that it was a similar CPU to the 'My Life' handheld, but it isn't. These 20 games are also found in the undumped Sunnyflyer 30-in-1

David 'MameHaze' Haywood @mamehaze.bsky.social · 13/06/2026

Odd font for the menu in this multigame, the 'y' character looks more like an 'x' with an extra unwanted dot nearby.

David 'MameHaze' Haywood @mamehaze.bsky.social · 10/06/2026

8-in-1 VT based device with apparently all the games in an internal ROM?! (there's nothing on the back of the PCB either, just this single glob) Probably can't be dumped. Surprising because I didn't think VT chips could have anything beyond the small internal boot ROM.

2131

David 'MameHaze' Haywood @mamehaze.bsky.social · 04/06/2026

some improvements were submitted to MAME's VT3xx emulation, and I noticed that the VT3xx version of Move Fun (and the various reskins of it) had a GFX bug with the lives counter (stars). Tested on a few real devices I have, and the VT3xx port is just broken on all of them. (this is 'fruit fall')

1112

David 'MameHaze' Haywood @mamehaze.bsky.social · 02/06/2026

found a 158-in-1 version of these st2302 based handhelds. doubt there are any unique games but it's an uncommon game count, and has a 'data clear' in test mode we don't usually see.

1114

David 'MameHaze' Haywood @mamehaze.bsky.social · 19/05/2026

Dillweed dumped an arcade game by Status Games called Planet Patrol. It's a very primitive Pac-Man style game. Not much known about it, same basic hardware as their early 80s card/casino titles (ie no sprites, just a basic tilemap) www.youtube.com/watch?v=2cnR...

The TV part of a Game Kid 85-in-1 was dumped. This is one of those weird hybrid systems where there are 2 systems in one. The LCD game is driven by one of the other globs that we have no way of dumping, the TV part is a VT03 system.

David 'MameHaze' Haywood @mamehaze.bsky.social · 01/05/2026

one of the most dishonest / scammy brick game packages I've seen. Box shows a unit with full colour screen. Actual device is your bog standard 99-in-1 monochrome affair, and nothing like what's shown on the box.

0162

David 'MameHaze' Haywood @mamehaze.bsky.social · 29/04/2026

Much to my surprise another XaviX based system was found, another Vtech unit. The Multi'Pilote is part of the Vtech '2en1' range, operating in TV and non-TV modes. This is a French release, but it might have been released elsewhere too under a different name.

1154

David 'MameHaze' Haywood @mamehaze.bsky.social · 28/04/2026

I reworked the SPI Flash handling for some of the ST2302 based handhelds, allowing them to show proper graphics. These contain games, or versions of games not in the already emulated units. Sound emulation is still awful though.

2204

David 'MameHaze' Haywood @mamehaze.bsky.social · 07/04/2026

toadster172 added preliminary sound to the LeapFrog Leapster emulation in their fork of MAME. Currently lacks voices, but music and SFX are there. I did a video www.youtube.com/watch?v=kJ0H... Note, won't compile if you rebase against current MAME due to sound system changes since fork

Cozy Coupe U-Drive uses a SONIX SNT110FG. Bit of a surprise, was expecting this to be an SPG29X based on it being an MGA game with scaling etc. (It's terrible, there's a video on YouTube from ZC Infinity if you're interested)

David 'MameHaze' Haywood @mamehaze.bsky.social · 24/02/2026

I thought the broken scrolling in the 'Helicopter' game on these BornKid / Beijeu units was a unSP2.0 core emulation bug (even if I'd traced the code extensively and couldn't find it) Nope, happens on hardware.

0153

David 'MameHaze' Haywood @mamehaze.bsky.social · 15/02/2026

strange Starbucks China handheld game, only has about 12 games on it though.

David 'MameHaze' Haywood @mamehaze.bsky.social · 12/02/2026

Monchichi 'Fluffy Puzzle' was dumped by PlasticFactory and Zak. This runs on a Sunwise board with the same VDP as many of the Toaplan shooters. It's unclear if this was released. It's a strange puzzle game where you link huggy characters to build pipes to reach the exit.

1111

David 'MameHaze' Haywood @mamehaze.bsky.social · 25/01/2026

First time I've seen one with this boot screen. It's ripped from the movie flyers, right?

1186

David 'MameHaze' Haywood @mamehaze.bsky.social · 19/01/2026

I got another one of those "HD 360 Degrees Rocker Palm Eyecare Console" systems. This one shows 2 checksums in test mode. I think it's slightly newer tech than the previous SunPlus based one. 1st Checksum completes more quickly, maybe internal ROM checksum?

I've added a bunch more pictures to the 'MAME 2025' page mamedev.emulab.it/haze/2025-ti... This only really scratches the surface of things that have been done, as many of the more obscure things are difficult to cover. Not everything shown is playable as it's meant to represent progress.

So Atari's Jammin' prototype has been recovered from VAX tape backups by SynaMax, Dutchman2000. I've hooked it up in MAME, it runs on some kind of Donkey Kong kit hardware with extra YM2151.

Some different 666-in-1 NES/VT bootleg consoles were dumped. The G6 only has Chinese/English The G7 has Spanish/Chinese/English The G9 (previously dumped) has Spanic/Chinese/English/Russian. The G6/G7 also show G6/G7 in the menu background, didn't notice that before.

David 'MameHaze' Haywood @mamehaze.bsky.social · 21/10/2025

One thing I didn't realise when the first of these Tou ma Pet devices was dumped is there are different versions of them (different OK-xxx codes, different case stiles) which presumably have different software. Here are 3 of them.

091

David 'MameHaze' Haywood @mamehaze.bsky.social · 18/10/2025

The Wiii3 was dumped, although I don't have proper controls hooked up yet (this is one of those where the code to read the controls is messy and is going to take a bit of figuring out)

David 'MameHaze' Haywood @mamehaze.bsky.social · 16/10/2025

Another high effort XaviX game was Champiyon Pinball from Tomy www.youtube.com/watch?v=6vBR... This again has some nice music with Ramacat's fixes, and I hadn't previously uploaded gameplay footage, only attract demo.

Another pair of XaviX highlights are the very obviously Sonic inspired Super Dash Ball and Gururin World, both from Epoch www.youtube.com/watch?v=GUCJ... www.youtube.com/watch?v=A0-0... Super Dash Ball uses trackball controllers, Gururin World is a tiny unicycle. Sound is improved in both.

..and if you play only one XaviX based game, make sure it's Geigeki Go Go Shooting. This shmup doesn't deserve to be a plug and play exclusive. Satoshi Fujishima formerly of Compile was involved in the development. The new sound emulation does it justice. www.youtube.com/watch?v=PRAL...
