Re: Saturn

a simpler system that uses the SH-2 (CPS-3?) The other "major" SH-2 platforms I know of are "Psikyo SH-2" (e.g. Strikers 1945 II/III, Gunbird 2, Tetris: The Absolute: The Grand Master 2, Sol Divide) and Kaneko Super Nova (e.g. Cyvern, Sengeki Striker, Gals Panic 4/S). Several of these games, predictably, have Saturn ports or sp...

Re: Some games aren't loading

This sort of thing can happen when ROMs are transferred over FTP in ASCII mode, or something else that does a similar conversion. For example, if converting newlines from DOS/Windows to Unix, ROMs that happen to contain the byte sequence "0D 0A" will be broken while those that don't contain that byte sequence will be fine.

Re: Saturn

All of what mic_ said, basically. People sometimes exaggerate Saturn's complexity to the point that it sounds like an utterly unfathomable beast of a system, but it is genuinely pretty complex. You have: Two SH-2 CPUs 68K (as a sound controller) SCSP synthesis/sample engine (Yamaha, but odd, i.e. not just an OPL3/4 core) SCSP DSP SCU DSP (custom DS...

Re: Advice for HDMI Users

Interesting. At least one room in my house has such a setup (ARC from the TV feeds into the soundbar, and turning the TV on/off also turns the soundbar on/off and vice-versa). Are you saying that if I plug my MiSTer directly into some other HDMI port on that television, that should be sufficient to reproduce the issue, i.e. the sound will come out...

Re: Advice for HDMI Users

Any idea whether that repeater somehow buffers/isolates pin 13 vs. passing it through, for those of us with setups that encounter CEC/ARC problems? No clue. How could I check? EDIT: Also, what are these CEC/ARC problems you are having? It's a series of issues that have been reported when connecting DE-10 Nano to a CEC-capable TV. In my case, audio...

Re: Arcade PCB System Reference List

This is a great resource, but be careful with it, because arcade systems are pretty loosely defined. Some come in multiple revisions or configurations, some have hardware split between shared boards and game-specific boards (e.g. games might share a graphics board but have different sound hardware), and occasionally a "system" is just peo...

Re: Is anyone working on Snow Bros. by Toaplan (or would fit any of the current cores?)

There's a note in the MAME driver that says "uses Kaneko's Pandora sprite chip (also used in DJ Boy, Air Buster ..)", so it looks like there's at least some significant overlap with the related Kaneko boards.

In the meantime, you might find Nightmare in the Dark on Neo Geo interesting.

Re: What type of SD card to get for MiSTer

so the PNY confirmed works with the mister but it only lets me use 460 GB instead of actually 512GB Most of the difference is because storage vendors (and the SI) say one gigabyte is 1,000,000,000 (10^9) bytes because the "giga-" prefix generally means 1,000,000,000, whereas RAM vendors (and most programmers) say one gigabyte is 1,073,74...

Re: Tandy 1000 Core

Judging by the Wikipedia article, "Tandy 1000" is almost more like a brand than a specific computer. Which models are particularly interesting? I know a bunch of DOS games had a "Tandy 1000" configuration (in the same sense that you'd configure a game for e.g. CGA and Sound Blaster), but I don't know if the common case was the o...

Re: Debugging/simulation?

Simulation seems like a great answer to specifically-designed scenarios - especially simple ones - but in a core that runs through millions of instructions before an issue arises, simulation isn't going to help - you will need SignalTap. I hadn't looked at SignalTap. I should probably dig into that a bit, so thanks for bringing it up. I recall rea...

Debugging/simulation?

I've been mostly out of the loop on FPGA workflows since college, and I'm wondering what approaches people are taking to debugging MiSTer cores and their components. Simply rebuilding the core and loading it is fine for minor tweaks, but for anything serious I'd obviously like some combination of more visibility and faster iteration. I also have so...

After changing the palette, press right in the main OSD menu and select "Save Settings". This retains the palette setting for me.

Re: PC98 core

Since the lidtw instruction added in 386 or later to the 0bbc address of ITF code is used, I think that this ITF code was saved from a model equipped with 386 or later. LIDT instructions were added in 286 (although most people ignored it because 286 protected mode is bad for DOS programs), and it was said that this code is from a V30 model. I thin...

Re: PC88 Core

I tried to compile it, but it didn't produce a .rbf file for some reason. I was able to compile the updated F68k core, however. I thought that I had answered this in my previous post, but I guess I deleted that part before posting. For whatever reason, the archived version of the project is not configured to produce a .rbf file. To change this, I ...

Re: PC88 Core

Can this boot at all without the I/O board? I get a blank screen, but I'm not sure whether I made a mistake with fonth.hex/boot.rom or the core just never starts unless it can mount the secondary SD card. edit: Okay, it gets to the ROM BASIC interpreter with "Mode" set to something other than "N". And then if I switch it back to...

Re: Msu-1

From what I remember of the original spec (which seems hard to find now), it's tricky to properly implement MSU-1 in hardware without independent storage devices for data and audio. Performing a data seek does not stop audio streaming, and vice-versa. So for full compatibility you need to be able to perform any pattern of seeking and streaming oper...
