I'm pretty sure ikari has said that the SD2SNES's built-in RTC is actually based on the SPC7110, so you can probably use that instead of reinventing the wheel...

Agreed, it definitely sounds like overheating, but that's not really an issue with the SNES, so my money is also on the caps.

I'm pretty sure the VMWare Tools for ESXi clients enables absolute positioning for mouse control, but without the Tools installed, it behaves the way you describe. Just curious, with this talk about the input code, have you figured out the issue with input not working after the machine locks or goes...

Since it was recently brought to my attention that bass v14 is along several of the static files missing from byuu's website after one of his last server migrations, I uploaded it to RHDN, and have it mirrored here as well: https://dl.qwertymodo.com/bass_v14.tar.xz

Something that would be incredibly helpful would be to make it easier and more straightforward to log or otherwise debug DMA transfers. Maybe a breakpoint that triggers upon the start of a DMA transfer to a specific destination, or triggers on the start of a transfer on a particular channel (I guess...

Almost looks like pad #2 from the U6 footprint is ripped off the substrate, but I don't know if that's even connected to anything. I'll have to take a look at my board once I'm home from vacation after the first.

Could be. Photos would help.

It's an inductor, not a resistor, and yes, it's necessary. Without it, I'm guessing you're getting a lot of noise on the clock, which could definitely crash the game.

Yeah, there really aren't any GPR's, at least not like what you'd see on other architectures. You have the accumulator, the two index registers, and that's pretty much it. It's designed with external memory in mind, which is why you'll see so many instructions with several different addressing varia...

You could probably do it by feeding (50MHz clock NAND DSYNC) into the clock input of a posedge-triggered (assuming active-high output on the NAND) latch with D0 and D1 as its data inputs. No inverter or delay necessary.

AliExpress has replacement 62-pin connectors for SNES with the actual correct pin spacing. They're only available in lots of 10, as far as I can tell, but $2 each is cheap if you can find a few people that want to go in on a group order. https://www.aliexpress.com/item/Replacement-62Pins-Slot-for-SN...

When I was actually ROM hacking, I'd find the gamepad polling code point. Then I'd run to that break point, and modify the value it stored immediately after the input was polled for the keypress I wanted. Then I would run the trace logger to capture the event I wanted that only happened after an in...

Just a minor detail, 1.54 had issues, 1.54.1 is what you'd want if you're upgrading. Or, if you want MSU-1 support, there's more recent git builds

For graphics to be referenced in code, I forgo ASCII/hex representations and just output a binary file with a corresponding .inc file that defines a label and a size viable and then includes the binary file.

Last time I checked, make friend failed on my machine, complaining that there's no rule to make target friend. Where do I find a working Makefile for this? If only it was as simple as man friend but alas, no such manual page exists. Nor is there one for man woman ... *sigh* adulting sucks. :P It is...
