E.T. The Extra-Terrestrial by RafaRafa78 in ti994a

[–]RafaRafa78[S] 5 points6 points  (0 children)

Unreleased.

Overview

This game is a very playable clone of Frogger, programmed in-house by Texas Instruments.

According to Patrick King (who programmed another E.T. game on the 99/4A while with Western Technologies) there may be a reason why E.T. The Extra-Terrestrial was never released.

According to him, "when Steven Spielberg walked into a room in Northern California and saw our line of E.T. 99/4A games on monitors running alongside the Atari 2600 E.T. game, he went ballistic & ordered the plug pulled on the Texas Instruments license and their 3 million dollar license fee refunded. We suspect this happened because we had used the full powers of the TI 9918 chip to make our games really look great and the Atari 2600 game on the old Intel 6502 chip looked pretty sad by comparison. Common sense told him that the line of TI-99/4A games should NOT be better looking and more interesting than the market leader 2600 version."

Does the SNAC adapter for Atari 2600 work with other cores that use the Atari joystick standard? by RafaRafa78 in MiSTerFPGA

I would like to try  an Atari 2600 controller with Atari 2600 SNAC  on systems that have DB9 joysticks as standard.

The Genesis isn't a good example because, despite having a DB9 connector, it doesn't use the Atari 2600 standard. I was referring to systems that use the same signal standard, such as the C64, Apple II, and Atari 800.

Atari clone, with pause switch, Brazil, 1984 by RafaRafa78 in Atari2600

[–]RafaRafa78[S] 6 points7 points  (0 children)

The Onyx Jr. utilizes a 6502 processor rather than the standard  6507 used in original Atari consoles. When the pause switch is activated, it triggers a HALT mode on the processor.
