Mesen doesn't seem to allow me to push A, B, Select, and Start simultaneously This is probably not Mesen. This is probably your keyboard =p Most do not register all of the keys all of the time. Some of the old school IBM PS2 port or high end gaming keyboards will register every key all of the time,...

I've encountered something that has me scratching my head. I have controller 2 mapped to some keys on my keyboard. Mesen doesn't seem to allow me to push A, B, Select, and Start simultaneously on controller 2. it will allow it on controller 1, but on controller two it will only register 2 or at most...

We've discussed SRAM tendencies in the past here. I think some do seem to power-on all 0 or all 1, but I don't think you'd typically find those in a conventional NES (but possibly in clones). PowerPak and Everdrive also initialize large parts of RAM with their menus, though not to 0 or 1. There are...

This thread has given me an idea. A game might be able to detect (somewhat inaccurately) whether it's running on an emulator or physical hardware by the RAM state. if the initial RAM state is all zeros, then the game could be pretty certain that it's running on an emulator. Of course, the opposite w...

I haven't reviewed it myself, but this very recently published fork of FCEUX is apparently attempting to make steam publishing of NES ROMs easy: NEStek: https://lowtekgames.itch.io/nestek Oh wow, that is pretty much what I was originally looking for. At this point I'm so far along with my own emula...

OK, thanks. That pretty much sums it up. I already exported MESEN's default palette and was already using it in my project. I just wanted to make sure nobody was going to get mad at me for doing so.

Does anybody know where MESEN's default palette came from? I ask because I'd like to use it as the default palette for my emulator/game as well, and I'm not sure whether I'd need permission or something from whoever made it initially. On one hand, it's just a palette...192 bytes of data. on the othe...

Shouldn't really be allocating a new texture every frame, instead you should update the texture.

Yes, that had occurred to me also.

Visual Studio 2017 community. short version: I got some code off of Stack Overflow for using a Texture2D and passing a Color array to it to draw my screen. I didn't notice that I had to Dispose the Texture2D on each frame. so my emulator was basically hanging onto each frame of video until the garba...

I mentioned in another thread that I'm building a custom emulator using MonoGame framework and C# in which to package my game rom for release on platforms like Steam that require the game to be a standalone exe file. After about a week of work, I have it running (not counting APU, I'm just going to ...

I'm pretty well committed to the course of writing my own custom emulator to wrap my ROM in. I've got it displaying nametables and scrolling so far (in grayscale, no color yet). I made some missteps in my CPU code, so I'm rewriting it to be easier to maintain. I'm having fun with it, and like I said...

I've already started on my custom emulator using C#/MonoGame and it's coming along OK. I spent the weekend working on it between chores and mountain biking. I'm a little conflicted about it. On one hand, I'm an experienced C# programmer (it's part of my actual day-job) and I'd been intending to lear...

APU aside, a barebones NES emulator would be pretty easy to write, and since you're aware of all the timing constraints of your own game you wouldn't even have to make the emulator particularly accurate in that regard. No need to bother with obscure quirks either, a simple 6502 core and a scanline-...

I apologize if this question has been answered previously, but I searched and couldn't really find the details I was after. How do you go about publishing a new NES game on a service such as Steam? Based on my initial research, it seems that they expect the game to be a standalone executable. Does S...

I'm 90% sure that my game won't be done in time, and I don't want to reveal it partially done. When I switched from CNROM to UNROM, I ended up getting deep into the weeds of graphics tile compression, probably way more than I needed to. It was a fun excursion and I learned a lot, but it stalled my p...
