Re: Startup LED Blinking Meanings

If the red and green lights are alternating and fading in and out, that's what they always do when the menu core is loaded.

Re: Sega Saturn Core in Development

Woah, did this guy build the CPU and the graphics chips both from scratch? Saturn has a pretty oddball CPU. All of the CPUs in the Saturn are normal CPUs: it uses a pair of Hitachi SH-2s, an SH-1, and a 68000. Maybe you're thinking about the VDPs? Most machines of this and previous generations used custom chips for the graphics, but the CPUs are a...

Re: Serial User Port (IO Board) Switcher

I'm not aware of such a switcher. You'd need something that is basically entirely passive or otherwise just routes a signal without expecting it to be USB. Nearly anything of this type would be expecting a USB signal, and that would likely do some damage to either the switcher or MiSTer.

The bigger issue with the N64 on MiSTer is how fast the chips run; the Saturn and PlayStation's chips run at about 1/3 the speed of the Nintendo 64's.

Re: Logitech G915 & MX Anywhere 3 in Bluetooth?

Both of those are Bluetooth LE/4.0, but the Bluetooth stack on MiSTer is absolutely ancient and doesn't support it, even if your Bluetooth dongle is also LE/4.0.

Re: FPS frames per second display

There's no such option since the FPGA is essentially running all the console components just like the original console did, and they weren't based on frames that you can count; they all run at the display frequency because their sprite engines are chasing the electron beam of a CRT. In this regard, a console core is always at either 30 or 60 FPS (o...

Re: Mario Bros Always Resets to title screen after starting Game

Totally just realized this was referring to the arcade game, not the NES game (NES core requires SDRAM). This could be heat-related if you have no cooling at all on your MiSTer; if you don't, I very highly recommend at least a heatsink, but the IO boards have fans as well to help keep things cool.

Re: Auto Save SRAM feature

On a real SNES, the console maps the SRAM to a memory address and when the game tells it to save the game, it writes the appropriate data to that address. On MiSTer, that's handled perfectly fine, but the save itself is not written to the SD card until the menu is opened and/or when you explicitly pick the save option in the core menu. When auto-sa...

Aside from SDRAM...

Because SRAM is stupidly expensive for anything more than a few hundred kilobytes. You'd easily be looking at $500+ USD for a 128 MB...

Re: stupid question: why cant you use internal rtc, by config?

Even linux has to get the time somehow; the DE10 nano has no onboard clock battery to keep time when it's powered off. The addon fixes that problem. If you want a clock without using the clock board, either use a wired or wireless internet connection so it can fetch the time via NTP.

Re: Script input/output error trying to Update

MicroSD cards don't have write protect switches.

It's hard to say what the actual issue is, but sounds like the SD card might be bad. I imagine if it were out of space or had a permissions issue, it would say so.

There's not really any pros to using a different filesystem. NTFS will cause headaches because various cores will need you to rename their games folders to match specific case-sensitivity.

It's that easy; as long as the drive is in a supported format (I'd highly recommend ExFAT), just have all your ROMs in the games folder on it, just like how they're structured on the SD card, but all you need is the Games folder.
