Oops...Should have mentioned I am outputing to my television and monitor at the same time (NVIDIA 7600GT in clone mode). Inside Stella's video options the highest available resolution is 1024x768 (Which is the highest I can output to the TV). Nonetheless, 720x480 with stretch turned on still looks best for resolutions 1024x768 or lower for my setup [Note: 1024x768 both with stretch turned on or off displays a smaller screen]. -Trebor

Video Settings: Renderer: OpenGL FS Resolution: 720x480 GL Stretch: Always The above looks best for my setup. I experienced the same "compressed vertically" affect to varying degrees with other resolutions. While some other settings left the screen "compressed" both horizontally as well as vertically. Try the above, hopefully it will work for you too. -Trebor

Not my work. Nevertheless, quite possibly the most amazing thing you will ever see and/or hear from the 2600. Video playing on the real deal available here: Main site here: http://www.pouet.net/prod.php?which=31535 Image attached here: 3lb_tj.zip -Trebor Edit: Oh yeah...And it's only 4K.

All the demos should have POKEY support provided the emulator supports POKEY completely. I only have used MESS for testing to I can't vouch for other emulators. --Ken Ken is correct. The issue is the emulator and not the dump. Same dump (CRC: 4ed4b7c0) plays POKEY sound in MESS, but not in ProSystem. Furthermore, respecting sound in Prosystem there are other issues (High pitch noises/lingering notes) which seem to minimize if I change the sample rate to 96000. Unfortuantely, the sample rate you select does not save when exiting the emulator and reverts back to 44100, once you restart it again. FWIW, the best version of MESS to use for Atari 7800 emulation is MESS 0.111. In version 0.111 you have the updated color palette and the older (MAME) sound core is still in use. In version 0.112 Atari 7800 emulation is broken. In version 0.113 (and newer) a new (MAME) sound core is used which causes sound problems for many people. -Trebor

Hi Bob, Problem/Missing Feature: In the Arcade version, if you hold down the fire button, you keep firing rapid shots in groups of four. In your hack, not a thing happens if you hold down the fire button (Outside of your ship firing the one initial shot). -Trebor

I am trying to get a video capture of a PAL screenshot, displaying all colors. Will post it here. This is my last update for a 'decent' palette for Stella, PAL mode has the same color stripes as the NTSC mode, but in the same order as the other palettes (Standard, Original Stella, Z26) ROM used this time is: Color Test (26-09-2002) (Eckhard Stolberg).a26 If you like the palette, PM me for the 'stella.pal' file, I won't post it yet unless you really want it, people. Please do post it, Nabuko78. Your palettes are always greatly appreciated. -Trebor LOL OK There you go. Also got updated palettes for 5200 (kat5200) and 7800 (ProSystem 1.2), I'm sure you'll apreciate it too, Trebor. stella.zip And that's my final update for color palettes for atari, hopefully. Thanks!

From whatsnew_0116.txt: Major Donkey Kong driver update: [couriersud] - Implemented discrete sound from schematics: dkong, radarscp - Implemented discrete background from schematics for radarscp and various effects: - blue to black to blue background - exact priorities - Grid will flip open and close, vertical flipping on hit. - Changed inputs for radarscp - Color generation from schematics (resistor mixer) for radarscp, dkong, dkongjr and dkong3 Additonally, in 0.116u3 the following affecting the dkong.c driver: "Created a new resistor network interface for computing palettes from color PROMs and component values on the PCB. Fixed several issues with the previous implementation. [couriersud] Donkey Kong driver update: [couriersud] - added sprite ram bank switching from schematics - combined memory maps - first attempts on decoding m58815 - radarsc1 driver for radarscope trs01 hardware - all drivers use VIDEO_RAW now - fixed cocktail issues - combined io and sound memory maps - implemented background handling (disable prom /CS line) in all dkong drivers Extended the flt_rc filter to support highpass filtering. Fixed the lowpass filter to actually do a lowpass filter. Hooked up the filter to King & Balloon and updated several other drivers to the new interface. [couriersud]" And lastly in 0.116u4 (Well, doesn't directly affect Donkey Kong, but dkong.c driver): "Fixed regressions in dkongjr and pestplce due to incorrect memory map and rendering too many sprites. [couriersud]" -Trebor

Fantastic work, Bob! I love that pressing down activates the shield - It's easier and less "Cramping" than hitting the second button. Although as mentioned, it can't hurt to add pressing the second button as an additional means of activating your ship's shield. Obviously, the backdrop is impossible due to the hardware video limitations of the 7800 - so going with the blank/empty black backgrouund matches the Arcade version best. However, perhaps there can be an Arcade Deluxe mode - showing what you currently have displaying while playing, and then maybe a 7800 Deluxe mode using a similar coloring idea as the 7800 Asteroids with a starfield backdrop (?) If not, I definitely perfer your current implementation copying the Arcade as close as possible. -Trebor

Any news on Pitfall II? That also needs to be emulated before I "leave" Stella...lol.

Thank you for working on this driver in MESS. No inconvenience here, Wilbert. I'm just doing what little I can to contribute. I wish I had the skills to work on drivers - 2600, 7800 and the sound syncronization issue are all emulations items I would tackle in MESS. Thankfully, you're doing an excellent job with the 2600. Keep up the fantastic work!

Whoops...should have provided CRC's for the 3 additional games/roms that crash MESS when loaded/launched: Stargate (1984) (Atari) - CRC: cde3530e Summer Games (1987) (Epyx) - CRC: b9cd3f86 Winter Games (1987) (Epyx) [!] - CRC: ddff6850

And make that all 3 Epyx titles crashing as Winter Games does the same thing...Just crashes out of the emulator.

In Warlords the "Green Lord's" defense appears as a graphical glitch spanning to the other side of the screen:

Tac Scan does not start a game - Just sits at logo...Unless I am missing something. Tried pressing all fire buttons and reset...Not a thing occurs:

Furthermore, just like the Epyx release California Games crashed out - So does Summer Games.

Additionally, funny about the games crashing issue is that just like Defender II crashed out...so does Stargate (Same game different releases/roms).

In Spider-Man there is a (black) graphic glitch that appears when Spider-Man is on the left side of the building:

Odd...Unless it is truly just Windows related. Just for the record, the same games/roms work without a problem in Stella (2.3.5). Regardless, if all works well in 0.117 then MESS will become my Atari 2600 emulator of choice...Although it would be nice if a workaround/fix for the sound sync (MAME core related) issue was implemented.

Miner 2049er Volume II does not display properly:

Q-bert's Qubes displays the following when loaded:

The Pitch is also incorrect when your shots hit enemies in Megamania.
