Trebor

Some perspective here. The mod became available from Best Electronics ~15 years ago: https://web.archive.org/web/20101119105730/http://best-electronics-ca.com/7800.htm Arguably, it was the first Composite mod of its time for the 7800, as it is based from the work that Atari Engineers performed ~20 years prior to that. So, it's a ~35 year old composite mod design. Best Electronics tends to keep things as close to back in the day availability/'realness' as possible. The site was one of the extremely few 7800 product offerings for a considerable number of years. That being stated, @-^CrossBow^- is meticulous and second to none in modification and repair services. He is highly recommended.

*UPDATE* Atari7800_MiSTer public Release 20240423 has been made available. It contains the following updates: -SDRAM signals and timing. -Palettes. -Miscellaneous system items.

Cross posted inquiry and answered in the other post. Difficulty Switch was in the position for the buttons to fire both weapons simultaneously instead of separate assignments.

Also to be fair, the 2600+ supports both the 2600 & 7800. Under the original 7800 hardware, the Difficulty Switch settings are physically reversed from the 2600. People with consoles under the original firmware with the Difficulty Switch settings reverse, may actually try flipping the switch to the other setting if not receiving the expected result. They would probably put 2 + 2 together and figure out the switch settings are reversed. One of the internal dialogue for such an individual, may go something like this: "Hey, my Space Invaders ship is still fat, but I have the Difficulty Switch in the correct position... Hmmm... Okay, let me try flipping the switch over... Yes, that fixed it! I guess the switch is mislabeled or set reversed. All I have to do is remember that fact going forward... Or maybe I'll check online to see if others are experiencing the same thing... There could be a system update for it."

The Retron is certainly an option, if the interest is only for the 2600. It does not play 7800 cartridges. The 2600+ handles all 7800 retail and almost every homebrew beautifully, including POKEY and YM sound support.

Pole Position II is actually a title that does not contain HSC saving code. This is the complete list of original retail titles that support HSC saving: -Asteroids -Centipede -Dig Dug -Food Fight -Galaga -Joust -Ms. Pac Man -Robotron 2084 -Xevious

@Alex_813 It could just be the power supply. I came across this video which demonstrates the issue: My primary Sega Genesis was experiencing the buzz-hum problem. I had another complete unit, swapped out the power supply and issue resolved. Same problematic power supply produced a buzz-hum effect to the audio output of the other unit as well. I don't know if it is a specific line of power supply that goes bad or has an issue, but what I can provide is from this picture and my experience utilizing two different power supplies under two different Sega Genesis Model 1 consoles: The 1602 Power Supply results in a buzz-hum produced via audio out which did change in loudness depending on the setting of the volume slider as well. The 1602-2 makes the console audio sound perfect. Regardless of the volume slider position, the sound is completely buzz-hum free. This may be $7.99 well spent. Over 7400 sold: https://www.ebay.com/itm/292577086494 There is another video I came across too. The guy replaced capacitors which resulted in the same issue with no change. After someone suggested a filter for the power, it then occurred to him to try a different power supply altogether, and problem solved. A nice technical explanation of the situation is provided:

DK PK/XM does something similar (Write POKEY @$4000/Reads ROM @$4000), at least in some if not all cases regarding physical cartridges built, @tep392 can confirm just to be certain. Those cartridge have worked fine thus far with the 2600+.

👍 Great call with having a shield meter. I am glad you ultimately agreed to that option. A one hit life is lost, 3 lives game is over, would be extremely difficult. Works very well with 1942, which features much less chaos, but not this title. Even with more total lives, losing a life frequently can build frustration and discouragement towards the game. It's also very disruptive towards the game(play) flow. Having a shield meter, and even a possibility to boost it, is exactly what this kind of 'mindless' chaotic shooter needs.

Depends how "technically" is being defined. "Technically" as closest accuracy to the original 2600/VCS hardware experience, that would be 2600+. My personal favorite and best of the bunch to me. "Technically" as easier to update to add 2600 games, while not being quite the original console experience, but having a menu to select games from, then it is the Flashback. "Technically" as spans the most Atari hardware platforms, and mimics closer to how a modern game system functions, then it's the Gamestation Pro. JetmanUK covered the various options in more depth, a few months back.

Have you seen The Perceptual Tuning Primer page? In short, "Perceptual Tuning refers to arranging TIA music in the key of A (specifically A3) with the intent to shift any poorly tuned notes to ones to ones aren't as easily detected as being poorly tuned." The Practical Application section explains a bit more: "The musical key with the best TIA Perceptual Tuning score for any 12 consecutive notes is A3@218.3Hz, and the A4 above it is good as well if you can avoid the major third at C#5@561.4Hz. When you use the key of A3 in your composition, you don't have to avoid the less-well tuned notes - the point of of this technique is we've hidden TIA's weaknesses where our ears are weaker. Just go ahead and write your songs in the key of A3 as if TIA was as perfectly in-tune, and you'll be taking advantage of Perceptual Tuning." There is a Samples section providing comparisons. @RevEngdid a fantastic job with the entire page. It is time well spent to read over the information, even if just for future reference and application. Hope it is helpful here though.

For those who do not frequent the Programming forum, @playsoft has released a WIP of Turret Turmoil: Dreadnought Assault, that playsoft and kiwilove have been working on:

Beautiful game - thank you for sharing it! Just time for the first dreadnought.

I've heard, the grapes (were) sour anyway, plenty of times with many of things. So some dude, knew a dude, who told him there was a bugged version released. The plethora of interviews Howard Scott Warshaw has been a part of without once ever stating or suggesting anything remotely like this concerning Raiders of the Lost Ark is evidence enough for me. If that is not proof enough, I can state that instead of Randy, I received intel from Jambi, who also knows, from Chairry and Globey, that the King of Cartoons has original source code of Raiders of the Lost Ark delivered by Reba the Mail Lady, who confirmed with Miss Yvonne that there was never such a bug. If still in dispute, Cowboy Curtis may show up with the red and blue pills. Take the blue pill if you still want to believe in a bugged version release. Take the red pill, if you know crack is wack, but the story is even wackier.
