Re: Mesen - NES Emulator

Hi Sour, if I have a LUA script which I want to run with a HD pack, is it possible to set a game specific script to run automatically as soon as the game starts? Thanks.

Re: Mesen - NES Emulator

I have a problem with <background> tag and it would be nice if you can change the behavior of this tag. Currently if the background image contains transparent area, then the emulator shows solid white in that area. Is it possible to change this behavior so that if an area in the background image is ...

Re: Mesen - NES Emulator

Hi Sour, I'm looking up HD pack tags in the online documentation using Chrome and some of them are too long to display in one line but they don't warp and there is no horizontal scroll bar. This one for example: https://www.mesen.ca/docs/hdpacks.html#lt-background-gt-tag Can you fix that when you ha...

Re: Mesen-S - SNES Emulator

I hear there's one guy who's even considering hires texture replacement packs for SNES tiles! :p To be honest, I'm still not convinced there's much point to it - the SNES has much less restrictions than the NES to start off, giving it more colors isn't that useful, and increasing the resolution ten...

Re: Defining a cross-emulator save state format

You might not have complete information needed for another emulator, but some things can be extrapolated. For example, if you have the current CPU or PPU memory map, you can fill in what the values for mapper latches should be. If you know the PPU raster position that the save state would happen at...

Yes, that is definitely a lot of work. But as all authors of emulators with save state functionality have done it already, why not spare newcomers from reinventing the wheel?

Re: Mesen - NES Emulator

The NES doesn't keep track of the total number of cycles, no, but emulating it properly requires knowing if the current cycle is "odd" or "even" for DMA/etc, so keeping track of the cycle count solves that requirement. Also, like supercat said, some mappers (and various other things) rely on the cy...

Re: Mesen - NES Emulator

I'm not too sure what distinction you're making between the "emulation" and "emulator" state? From my point of view, 99% of the content of save states is vital "emulation" state. For example, the real NES hardware does not keep track of how many CPU cycles have passed since running the game so the ...

Re: Mesen - NES Emulator

In a recent feature request and a recent commit, breaking save states compatibility is mentioned. So is it possible to split the save states into 2 parts? One part contains the emulated game state and the other part contains the emulator state. The emulated game state format should be standardized f...

Re: HD mode 7

My concern is how to mix this with upscale filtering of other objects on the screen. To my understanding, the whole screen is sent to the filter as a single picture and the filter with upscale the screen as a whole. This won't work now that the screen becomes two parts with different resolutions. Th...

Re: Demo. Fzero like game on NES.

looks like it is curving up The map is actually very small, so I manually adjusted the distances per tile. The top most tiles should be further away, but since the map is so small, it would usually be off the map (for the top few tiles), making the resolution look even worse. Anyway, my manual adju...

Re: 3DNes

Is it possible to set some background tiles to use the background color in place of transparency? For example the brick wall background in level 2 looks odd with the bricks floating in mid air. Otherwise the game looks fantastic.
