#
# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
#
# (3) This script is generated from the Groovy template
# https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
# within the Gradle project.
#
# You can find Gradle at https://github.com/gradle/gradle/.

# J65el02 Machine
A java app to test the J65el02 implementation of the 65el02 cpu originally created by Eloraam.
# Credits.
Eloraam - Original cpu, providing permission to Bigfoot for their emulator. - http://www.eloraam.com/
Bigfoot - Original emulator in C, rpcboot.bin, tetris.img, slideshow.img, and redforth.img - http://bigfootinformatika.hu/65el02/
Simon816 - Creator of J65el02, the implementation that without this machine would not be possible. - https://github.com/simon816/J65el02
Timmie3054, Amon, Pcmaster160, CadenDonuts, and HanFox - Original source of the font which I have used in this emulator. https://bdcraft.net/community/viewtopic.php?t=354
# TODO:
Speed up monitor rendering
Discover intended clock speed for 65el02
Replace font with an original font?
Actually make a minecraft mod.
