New email address, article update and source release
|
2008.08.10 |
|
|
 Please note that I've got a new email address (to
reach me, check this page). The old one
@club-internet.fr will be discontinued at the end of the month, my previous
Internet provider being stopping the contract.
The article on
number rounding has been updated.
I also released the
Pampurfe's Buzz machine source code at the
request of the Zzub developer community.

ay2wav 1.10 update, z80span and ay2sna release
|
2007.04.04 |
|
|
ay2wav has been updated. What's new?
Amstrad CPC speaker emulation, for more realistic
sounds, with different quality settings,
Debug mode, to ensure musics are correctly ripped
and/or encoded,
Possibility to fix tonality of early AY3 tunes
ripped on CPC but modified in order to work as if they were played on a ZX
Spectrum,
A few bugfixes
I also released two other tools for AY3 chiptune hacking,
z80span, a program to report Z80 code
coverage, and ay2sna, a program to convert
an AY3 file into a memory snapshot for Amstrad CPC emulators.

Captive God 1.01
|
2007.01.28 |
|
|
I've just released Captive God.
It is a help program for
Captive.
Captive is a game working on Atari ST computers. You can run it on a Windows
PC with an STE emulator called STEem.
Captive God is plugging into STEem to interract with Captive when it's
running.
The main Captive God feature is the path finder, which shows on a maze map
the path to a user-selected location. It takes into account clipboard
collection and locks to open required to reach the desired position.
The second feature is the Monitor, a small window to be put on the top of your
emulator screen. It shows you the direction to take to follow the programmed
path, and the password/bar/button codes to open any door. Normally, it will
show only puzzle solutions which you have found, but you can force it to cheat
and reveal any code.
Captive God is quite similar to and has been inspired by the
Super Captive
Companion (SuperCC), by Pierre Fournier. A few icons were just lamely
ripped from it. Thanks to everybody who contributed to this project (ideas,
reverse-engineering, pieces of code, etc.)

ParamEQ source code released
|
2006.11.09 |
|
|
Paniq is developing an open source
Buzz clone called
Aldrin.
My ParamEQ Buzz plug-in seems to be
pretty popular, so he asked me to release the source code in order to have
it in Aldrin.
So I released the source code under the
LGPL license.

J'ai publié un petit
résumé de ma dernière lecture, « Que la
crise s'aggrave ! » de François Partant.
Livre très intéressant, ma foi !
Merci à Paul des
R.G. pour le
prêt du bouquin.

Added AY2Wav utility + source code
|
2006.07.15 |
|
|
I just completed the AY2Wav utility,
something I was developping from a long time and which I never finished until
today... .AY files are music files from Amstrad CPC and Sinclair Spectrum
computers. They contain music data as well as the code required to play it
back on the original computer. This program emulates the Zilog Z80
microprocessor and the General Instruments AY-3-8910/8912 (or Yamaha YM2149)
Programmable Sound Generator, in order to render an audio sample file in the
Wav format. Currently there is no support of the ZX beeper, so some tune may
be silent or not working at all. The program features a high quality
resampling system, something which is missing in most AY players or CPC/ZX
emulators.
The Z80 emulator code is from Marat
Fayzullin, I had to modify it a bit in order to make the I/O functions
work correctly. Also, I got special tricks for the AY-3-8910 from the
MAME project.
YMEmu by Bulba S.V. contained
helpful information to distinguish between CPC and ZX because I know nothing
to ZX/Spectrum! You'll find a lot of .AY files
there.

Update for the article on number rounding
|
2006.06.17 |
|
|
My article on number rounding has been
updated to fix a few typos.
|
|
FFTReal 2.0 and Stopwatch 1.02
|
2005.10.18 |
|
|
FFTReal has
been upgraded to v2.00; the class has been templatised to accept any kind of
floating point type for data. There is also a new template class for
fixed-length FFTs, giving a significative speed improvement. The license has
been changed to LGPL.
Stopwatch had
its interface changed a bit to something simpler.
