Jo-Engine release / Release 7.0
« on: April 12, 2017, 02:18:15 pm »
Hi  :),

A new update is available with dual CPU support and Sega Film/Cinepak support  :D

You can also change Jo Engine option on your makefile (I removed all options from jo/conf.h)

Warning, after update your program may not compile.

Don't worry, just follow the instruction on jo/conf.h or look at the makefile on Demo1  ;)

General Jo Engine Help / Read file asynchronously without blocking the game
« on: September 18, 2016, 08:36:45 pm »
I added some functions to read file asynchronously, because I working on a video reader, but it's working for any file and any usage :)

If you're interested, here 's how it works:

The function bellow will be called when the file is loaded:

Code: [Select]
void            my_async_read(char *contents, int length, int optional_token)

To read a file asynchronously, you just have to call jo_fs_read_file_async() with the filename, the callback and an optional token (user value for the callback)

Code: [Select]
jo_fs_read_file_async("DEMO.TXT", my_async_read, 0);

In attachement, you will find a sample code to load a background image (TGA) from the CD asynchronously

Jo-Engine release / New version 4.7 with bugs fixes
« on: September 12, 2016, 06:51:30 pm »

Other release / Yabause 0.9.15
« on: August 30, 2016, 02:39:32 pm »
Cool there is a new version of Yabause  :D

Arguably, the most notable features of this release are:

– Low-level CD Block emulation
– CloneCD file format support
– High resolution for the software renderer

We also included code from other great projects:

– Musashi 68K core (code by Karl Stenerud)
– SSF sound format playing (code by R. Belmont, Richard Bannister, Neil Corlett)

As many of you should already be aware, Yabause was forked into a new project,
uoYabause, by devmiyax. We included some of his fixes back into Yabause.

Due to lack of maintainer, this release will be the last to include a gtk port.

Since our last release, we also improved our tools:

– Automated builds for linux, mac and windows
– Development builds pushed after each commit
– Translations on Transifex
– Compatibility reports on our wiki

Download link:

PS: I will update Yabause in Jo Engine repository
