bedrock-pc, branch v0.3.1Bedrock emulator and assembler for Windows and Linux
https://code.benbridle.com/bedrock-pc/atom?h=v0.3.12024-04-16T03:29:22ZUpdate version to 0.3.12024-04-16T03:29:22ZBen Bridlebridle.benjamin@gmail.com2024-04-16T03:01:17Zurn:sha1:2adb82b9ddb3e753bc7f4ea6d22c332bc5d783a2Fix memory, input, screen, and file devices2024-04-16T03:29:12ZBen Bridlebridle.benjamin@gmail.com2024-04-16T03:27:45Zurn:sha1:a07d1585deb41bc40777045ac36b1643d2574980
The memory device was never being allocated any memory, the input device
wasn't scrolling correctly, the screen device was rendering sprites
incorrectly, and the device ID of the file device had not been changed
over from 0xA to 0x9.

This is a complete redesign of the file device. The most notable
addition is the ability to ascend and descend the file tree.
Prevent overflow errors on stream device pointers2024-01-30T18:37:54ZBen Bridlebridle.benjamin@gmail.com2024-01-29T05:33:58Zurn:sha1:30d2f099c9edf4f59fbbdd6686988ae7b0622ba2
The stream device pointers now use wrapping semantics in order to
prevent overflow errors.
Change stream device to use buffered streams2024-01-30T18:37:54ZBen Bridlebridle.benjamin@gmail.com2024-01-29T05:31:45Zurn:sha1:e4cdcf4f5082f90abd9e259ccc215ecbb1973ab5
Wrapping stdin and stdout with BufReader and BufWriter makes reads and
writes more efficient by bundling multiple characters into a single
read or write operation. In practice, this hasn't made a difference to
running the numbers demo, but that demo spends the majority of processor
time converting values to decimal strings.
Refactor code without changing functionality2024-01-30T18:37:54ZBen Bridlebridle.benjamin@gmail.com2024-01-28T01:31:12Zurn:sha1:521e525763723cbc5d65b37ff47f34af48f50a2f
An effort to make the code shorter and more readable. This mostly
affects the code for the clock device.
Change clock cumulative timer to use 256th ticks instead of seconds2024-01-30T18:37:54ZBen Bridlebridle.benjamin@gmail.com2024-01-28T01:20:59Zurn:sha1:a4d06fd54ab22bbdd6b0dc9d5af199fc8be13591
The "Cumulative seconds" port of the CLOCK device has been changed
to be called "Cumulative timer", with the units changing from seconds
to 1/256 second ticks.
Release version 0.2.02024-01-30T18:37:54ZBen Bridlebridle.benjamin@gmail.com2024-01-30T18:36:37Zurn:sha1:b10c26cf6b10eab4bd4847c27c7b4d65001d51b7
The bedrock_core update is a significant breaking change, so the
version number needs to be incremented.
