I did a search and this appears to be the latest topic on Mednafenx NES, so I'd like to point out some serious flaws with this version.
I write for Hardcore Gaming 101, where screen fidelity is of the utmost importance. Emulated screens must be 1x1, in perfect ratio, with no filters or other such gimmickry.
Up until now I've been using MednafenX NES V9, the only problem being when you take a screenshot, what it actually grabs has scrolled downwards by about 8 pixels. So you get a black bar at the top (or in some games, whatever was being drawn in that otherwise blank area).
Note how the bottom of the screen is cut off? It's still 224 pixels vertical, but it's scrolled down a bit.
Here's how it SHOULD look, taken on FCEU for PC:
Notice how the stats at the bottom are correctly aligned? It's 224 pixels in height, but the screen capture ended at the correct place, grabbing the entirety of the bottom of the screen.
With this stage of Vice it's OK, since the game is drawing the top in to scroll down, so you don't notice, but in another game, such Samurai Pizza Cats, you end up with a hideous balck bar at the top and the bottom cut off. Obviously I can't use screens like this.
So I decided to update to V15 of this, and I discover the palette has been screwed up:
Look at how muddy and washed out it is, with a kind of orange tone to it. What is this?!
I can't play it and I can't use the screens. It's hideous. Notice how vibrant the colours were in the first two screens. And worst of all, IT'S STILL SHIFTING THE POSITION OF THE GRAB, so I again end up with the bottom cut off.
Madmab, I appreciate the work you put into this, but I have had to revert back to V9. I don't know how anyone could play a game with the wrong colours. Both V9 and FCEU have the same colours, very vibrant and beautiful to look at.
For both MednafenX experiments I deleted the SAVE directory and defaulted the settings, and booted the ROM both times in default mode. I did not alter the palette options. Somewhere along the lines you must have changed how the emulator core or whatever renders the graphics. After taking this screen I did try altering the palette options, selecting autogenerate and other options, but this screwed it up even worse! There does not seem to be any way to get the V15 emulator to render colours like the V9 emulator.
Is there any chance that both of these problems could be fixed? I can use V9 for the correct colouring, but that means I still need to switch to PC emulation for taking article screenshots.
Without taking more screens and FTPing them to my PC to upload, here's another game on our server I took with the bar at the top. The background is black, so you don't notice it very much, but just LOOK at how low down the status bar is? Somehow when you click capture on Mednafen, it doesn't start at the first NTSC scanline (#8), it starts at 0 and then stops short, cutting off the last 8 lines. If you need more images to illustrate this I can take some. But right now Mednafenx is useless for actual work.This post has been edited by Sketcz: Feb 16 2012, 06:02 PM
