Re: Trouble Running Knuckles in Sonic 2 on Mister FPGA - Black Screen Issue

There's a working Sonic 2 & Knuckles rom with a md5 hash of bdd13934f4f31bf4d849ef8597d4a07c. I checked it against the rom listed in No-Intro's database (Sonic & Knuckles + Sonic The Hedgehog 2 (World) (Rev A) (Lock-on Combination)) with a hex editor and it differs in exactly 4 bytes.

ROM cartridge support is probably a very low-priority task for the Saturn core, though (only two games use them, and both have patches available to use a RAM cartridge instead).

Both Ultraman and KoF 95 cartridges have been supported by the Saturn core for a long time now. No need to patch discs to play them.

Re: Ballblazer C64 NTSC

An update on the Ballblazing situation, the newest version of the core not only makes the Remember cracked version playable in NTSC, it even boots the original .g64 disk images. Now the third best version of the game can be played in its original intended speed.

Re: Castlevania - Symphony of the Night (v1.0)[Meduza Team]

The color of PCB has nothing to do with board versions. Different vendors make boards out of different materials. For example, https://MiSTerFPGA.co.uk uses black PCBs for all their products.

SDRAM board has a copyright notice on it, the board revision is also listed there. If your board is v2.9 or newer, it should be fine for the Saturn core.

@pac the obvious CP that prevents boot entirely, agreed - UniBIOS doesn't do anything for the ones with in-game protection.

Are there any examples of obvious in-game copy protections checks? Where game works at first but then suddenly stops.

I am surprised to learn that Alien 3 for Master System seems to run fine on the Nuked-MD core. This game is notorious for not booting at all on actual Mega Drive consoles. Is this a bug, or was something intentionally tweaked in the core to make this game playable?

Re: Ballblazer C64 NTSC

I found a peculiar thing. Setting the Turbo mode option to "Smart" makes the core pass the Lucasfilm Games screen. What's even more interesting, the same trick works even on a .g64 of the original game disk! There's a catch however, as the game's GUI shows graphic corruption. So the game is playable but not in a 100% perfect form.

No luck with C128 core. Freezes with C64 mode option set to either "pure c64" or "C128 extensions".

Also, I read the docs attached to the REM version and they say that the game was cracked from disk, not a cassette. Why would it access the motor then? Weird.

Re: Super Game Boy SNES core with MSU

It's a Game Boy bootrom (also traditionally mistakenly called "BIOS") stored inside the Super Game Boy cartridge, similar to bootroms you can load in the Game Boy core. The .sfc file is the SNES part of the SGB rom, .bin file is the Game Boy part of the SGB rom.

Re: Sega Saturn Core in Development

Most likely that accurate analog video output timings are of lower priority currently. My CRT also displays Saturn shifted to the left, but the image signal itself is very stable. This will be probably tweaked some time later.

So, as I understand, MCR3 is a true interlaced video system (480i), and MiSTer core outputting progressive 240p video on analog display is an imperfection of the core?

Re: Tapper Arcade Video Resolution

Currently the core outputs video with the these specs: 511x240, 15.78KHz, 59.7Hz. The picture is clearly in progressive scan with blank scanlines every other line. The core also has an option titled "Deinterlacer Hi-Res" which, I assume, turns the video from 240p to 480p, making it lose sync on 15KHz TV.

Does anyone with the knowledge of vintage arcade games know if the analog video output of Tapper in MiSTer is accurate? The core outputs 240p image with noticeable flicker on sprites.

Re: Commodore 128 for the MiSTer?

VDC output works now on a CRT TV. Infocom's text adventures look sharp in NTSC. Running a PAL demo I can see pixels shaking very slightly, but I don't know how image looked on real hardware to judge it properly. I heard that VDC's output spec could be stretched pretty wide by programmers.
Thanks for the update.

Re: Best Wired USB Sega Saturn Controller Clone and Other Controller Options

Retro-Bit USB controller is pretty good but it has a peculiar edge case scenario flaw: it does not register Start+A or Start+X combinations as those are reserved for Dinput/Xinput mode switch functions. I know that there are games on the Saturn which use Start+A+B+C for soft reset, so that might cause an issue.

Re: Controls for Hyper Sports and Hyper Olympic?

Is it possible to implement so that the core automatically detects Hyper Shot controller requirement from rom's NES 2.0 header and maps NES A and B to Hyper Shot Run and Jump respectfully? This way there would be no need to add yet another niche controller option to OSD menu.
