Sun 3rd January 2021

- Changed the Oricutron default settings to declare the presence of a IJK joystick interface and two SDL joysticks.


Wed 9th December 2020

Thu 20th February 2020
- Upgraded ym2mym to version 1.8 (New retuning options supporting Spectrum and MSX machines)


Sat 7th September 2019
- Upgraded the C compiler to version 1.38 by integrating all the latest changes from Fabrice Frances: Fixes some issues found by Goyo and Retroric regarding encoding of data tables by the compiler.

- Fixed a problem with include/sys/sound.h containing invalid symbols that don't compile correctly


Sat 8th June 2019
- Upgraded the C compiler to version 1.36 by integrating all the latest changes from Fabrice Frances:

- Changed the default compile optimization level from -O2 to -O3 - providing significantly better code generation, both in size and speed
- The code generator macro file is now compatible with both XA and FRASM

- Tap2Dsk 2.1.1: Added a fix to avoid the tool to stay stuck on tapes with incorrect size specified in their headers
- Fixed a problem with itoa not correctly processing negative numbers (the '-'' was overwritten by the number printing routine). Also took the opportunity to optimize the code (removed the jsr itoa / rts as well as an unnecessary x register clearing (it's set to zero when we are back from udiv10)

- Fixed the BomberZ samples program to use the new Bas2Tap syntax
- Fixed the library functions 'scanf' and 'sscanf' (For some reason these files had not been converted to use the XA syntax when we switched from FRASM)
- Upgraded the version of Sedoric 3 used by Tap2DSK with the patch that improves the handling of the "insert master disk" prompt
