RMT 1.28 Patch 8 & Programming

analmux · February 25, 2015

I removed the original topic here. It gets lost too fast on the main 'Atari 8-Bit Computers' forum.

• AtariAge Forums - Atari Systems - Atari 8-Bit Computers - RMT Patch 8

----------------------------------------------------------------------------------------------------

Here is the official RMT 1.28 Patch 8.

See the attached zip-file. One test-file included: "Test1" (Test1.rmt and Test1.xex). Any questions? Answers & other examples will be next time.

And here are some background topics:

• AtariAge Forums - Atari Systems - Atari 8-Bit Computers - RMT 1.28 Patch 8 theory

• AtariAge Forums - Atari Systems - Atari 8-Bit Computers - RMT 1.28 no bugs?

• AtariAge Forums - Atari Systems - Atari 8-Bit Computers - How to improve the PoKey "NOTE-2-PITCH" table, compared to RMT.

• AtariAge Forums - Atari Systems - Atari 8-Bit Computers - More about PoKey 16-bit mode and 'distortion guitar'

----------------------------------------------------------------------------------------------------

Here's the final table schedule:

Patch 8 Table:

Here's an 'Overview Orchestra', more details of the final table schedule. It is a detailed scheme table scale of all the Patch 8 positibilies:

	PoKey distortions:
