(Español abajo) Yie Ar Kungfu is an old Konami title, very popular among 8-bit users -both console and microcomputers. It's the earlies SF2-like game you can find. The title means: one, two, Kungfu! And it's full of funny moments, like when you hit a male opponent's nether parts and salute them with

Unlike CPS, where a consistent protection system was used for all games, SEGA System16 had many hardware variations with different protection schemes. Some games have encryption in the M68000 of two possible types; others have it in the sound CPU, others have an MCU messing with the CPU. And a few o

Summary: -New Konami core: MX5000/Flak Attack -MiSTer: unzip the attached mister file directly on the root of your SD card, OR run update_all and copy jtbeta.zip to games/mame manually (only if needed). jtbeta.zip is inside the mister zip file. -All files are also stored in the Discord #betafiles ch

Important: copy the attached jtbeta.zip file to games/mame on MiSTer After the Exed Exes detour, we come back to System16 to continue increasing compatibility. This week has been focused on solving strange flickering and palette issues with Dynamite Dux. The root cause was in a CPU-related module th

I started this week trying to get System 16B games working, but I came across the i8051 MCU again. This MCU is used in many arcade games, and I have already faced it in the past. There are no good open-source cores for it. At least, not good from our retro point of view. I haven't been able to make

Hi all, I have too many news this week! -New System 16 beta with four games added: Wonder Boy 3, Phantasy Zone, Action Fighter and Alex Kidd.

However, I must say that it is still not perfect. A bug makes Mars Matri

(español abajo) This week's update comes with a ton of internal changes. First, the SDRAM is now operated at bursts of 8 bytes, so graphics information is transferred in a single request. Together with other improvements, this change has boosted the number of sprites per line, and the X-Men COTA sta

(español abajo) I had fixed, improved and strengthen many core features not just during the week but during the last two weeks. So, I was looking forward to this update. But, in the tests before bringing this to you, I found a couple of graphics issues that could also be hiding elsewhere. I didn't e

(español abajo) This has been another busy week of catching bugs, trying to close the core development. There are four types of problems left: 1. Graphic glitches due to SDRAM congestion 2. Raster and row scrolling effects not working well together 3. Odd behaviours that could point to a bug in the

(español abajo) It has been a very intense week as I am ironing out the little things pending in the core. They are little, but they are the toughest ones! The only worrying one is Gigawing because, in a couple of scenes, there is a moment when the SDRAM fails to deliver all the sprites, and some li

(español abajo) We finish three series of games this week: -Dungeon&Dragons, by adding Shadow over Mystara -19XX, by adding 1944 -Street Fighter Alpha, by adding the third game Plus Janpai Puzzle Choko, a title in Japanese, but you don't need to understand the language to play.

Please get the files from the latest beta post (español abajo) My first core after starting Patreon was 1942. It took me about two months to complete it.

Amstrad version was very good an

FILES ATTACHED. We're finally here. The last beta file brings suppot to what was the first CPS game: Forgotten Worlds.

FILES HERE Smooth animations, new game elements and a full art gallery, that's Pang! 3.

You will see that many of the s

(español abajo) After much struggle, I have moved the memory controller to a 96MHz clock. This had large implications in the system. For those developers out there, not the whole core is operated at that speed, part of it runs at 48MHz in order to ease synthesis. Much of the time this week has been

(español abajo) After three weeks of intense work, here it is for your enjoyment: Double Dragon! The core follows the original schematics, which I eventually found, and there are no compromises regarding accuracy. The only point I need to check is whether the 6801 CPU core used is really cycle accur

As you requested on last month's poll, I have worked this month on Black Tiger (beta files here). This is an awesome RPG-ish arcade game from 1987. Manuel Astudillo had sent me this PCB too as he is very fond of this game. Thanks Manuel! Technically speaking, the game uses the same object (sprite) e

Tiger Road PCB has an empty socket for an intel microcontroller (MCU). Also some chip footprints are drawn on the board, but the chips are not there. If you fill those gaps you will just get a F1 Dream PCB! Yes, it looks like these two games shared the same design! It has been rather easy to make F1

Here it is, resurrected from the PCB era, the 1943 arcade from CAPCOM. This is an awesome game with a lot of technical improvements over the prequel 1942. This has been a bit easier to do than the previous two games as I am getting more used to CAPCOM technology of the time. This beta version has tw
