But I do believe that it's not 5V and 15V simultaneously, and that marking means it can be either. Or possibly anywhere in-between. Yeah, so, i'm not feeling brave enough to just start throwing power supplies at it... Nintendo is not known for being standards compliant, and ...I just don't have the...

Do you have a friend you can borrow their power supply from? It'd be interesting to try replacing yours with some other source of 15V and see if that changes anything. I don't have any i can borrow from anyone at the moment... hmm... It outputs 5v @ 1.5A and 15v @ 2.6A, i don't think a USB-C phone ...

Is the Switch power supply plugged into the same outlet as the amplifier is? Yes. I tried playing with power: Same outlets, different outlets, in an audio receiver, in capture device, and directly to independently powered pro grade studio monitor speakers each with their own power supplies. No luck...

In headphones, or are you plugging it into a sound system? Ok, headphones do not buzz. I tried a few stereo receivers and an capture card and they all buzz at varying degrees of somewhat awful. Volume control on the switch (i think its digital) has no effect on the level of buzz. It sounds like 60h...

I know there are tons of talented EE folks around here. Question: My Nintendo Switch buzzes a ton through the headphone jack, but only when it is docked. Researching tells me this is a somewhat common problem and i need a "ground loop isolator" to balance the DC... or something. Is this something i ...

I've never really debugged an NES game before (mainly a C64 developer).

Mesen is Wonderful.

Do you have any test maps drawn or rendering?

is it faster and or more space saving to do X or Y Always situational. I use this instruction reference with byte and cycle counts: https://www.masswerk.at/6502/6502_instruction_set.html Branch instructions are faster and smaller than a 16-bit JMP or JSR, but, they only have a range of -128 to 127 ...

- Count down instead of up: if possible, have your loop counters start from the highest value and decrement them down to 0 or -1, so you can use the CPU status flags Z or N, respectively, to detect the end condition, without the need for a CMP/CPX/CPY instruction per iteration. You can also count a...

You know, the LUA works fine and all but it detects any kind of sprite overflow, without being able to tell general overflows apart from those that are being used to achieve masking effects. It only detects what scanline the sprite overflow flag was set and draws it. The flag itself is prone to fai...

the lua script you provided and it works nicely! Thanks for that. Awesome! Could you possibly provide a version that works (in BizHawk)? No. Sorry =( I am using the Mesen specific Lua API to make that script work. I have never used bizhawk. The code is only 30 lines long though; it might be possibl...

i know how to hack mario games Awesome! Did you post any of your work on romhacking.net? I love playing them. I compiled and ran this SMB1 disassembly in the Mesen debugger a few months back. Fun times! You could really make some awesome hacks with this... https://pbs.twimg.com/media/EUF2V0VVAAYl2r...

Something like the metatile IDs are loaded into a buffer, and in NMI I have a routine that takes the 4 tile bytes stuffed in the ID and shoves it through ppudata, and moves onto the next ID It's fast to use 2 buffers and stuff one with the tops and the other with the bottoms of the metatiles when s...
