Licensing is unknown and you are +certainly at risk if you distribute these in a commercial product. +My recommendation: For your personal use only. + +z80sim +^^^^^^ + + This is an emulator for the Z80 instruction set. It is based + on the instruction set emulator by Marat Fayzullin but has + been extended to load Intel hex format files as produced by + the SDCC toolchain. + + Sources and licensing + ^^^^^^^^^^^^^^^^^^^^^ + + Marat Fayzullin's Z80 instruction set simulator is available + here: http://fms.komkon.org/EMUL8/ . Licensing information + is available at that site as well. I am not permitted to + distribute that package on the internet, but the Makefile + will automatically download the package. + + Most of the Intel hex logic was copied from some + http://www.pjrc.com/tech/8051/pm2_docs/intel-hex.html . + Licensing requires only that I include the authors name + (Paul Stoffregen) and contact information (paul@ece.orst.edu) + in the source code. + + |
