30/06 - DSP Emulator 0.10b1 WIP 29/06
General:
UPD765 - Added some of the specifications EDSK v5: added emulation of the 'weak' sectors (multiple copies of the same sector) and corrected the specification of the 32K sectors ('Corsarios', 'MOT', 'Robocop', 'Buggy Boy', etc.).
Spectrum+3:
Understood in detail SpeedLock+3 copy protection. If the disk image does not include copies of the 'weak' sectors, the emulator simulate them. Understood also the 32Kb sector Opera disk protection. Modified image of 'MOT' for testing and is working properly.

I'm sorry about the lack of updates, but real life leaves you sometimes exaust (and even more if you get sick). Here is a picture of my next target:

12/04 - DSP Emulator 0.9b5 WIP 12/04 released.
At last BubbleBobble has sound!
Many bugs fixed on YM2203 and YM3812 timers (finally undestood how they work!). Many drivers work with correct speed with no CPU clock hack. Most obiuos is 'Toki', now shoot sound, jump sound, etc sound at correct speed. Removed hacks from 'Toki', 'Wardner', 'ShootOut', 'SnowBros', 'Express Raider' and many others.
Added driver for 'Circus Charlie' and 'Iron Horse', both with sound.

Continue improving input system, added joystick, by now you can select only the first joystick (even you have more, and it's listed in the configuration menu).
Reviewed all drivers and added all entries (second coin, start and player).
Added controls in Tehkan Worldcup, and now it's playable.

26/03 - DSP Emulator 0.9b5 WIP 26/03 released.
Improved keyboard system, one of the most wanted changes. Now the keys can be redefined (general configuration menu) and added second player controls, and two players can play together (BubbleBobble, ExedExes, etc). The joystick is disabled for now due to internal changes. Reviewing all drivers to add all entries (second coin, start and player).
Also added Gun.Smoke and added many opcodes to TMS-32010 CPU, you can finish Wardner now.

16/03 - DSP Emulator 0.9b5 WIP 15/03 released.
Added Exed Exes, preliminary driver for Big Karnak and small fixes for TMS-32010 CPU.

15/03 - I'm sorry, but DSP WIP will be delayed some days. Here in Valencia we are celebrating Fallas 2010, up to 20/03, at last some holidays!! Maybe I release a new version before weekend... but I don't know.

09/03 - DSP Emulator 0.9b5 WIP released.
Finally I found the huge memory reservation bug!. It was the TAPE module, that reserves 12288 (tape blocks) X 131070 (size of block)=1,6Gb of RAM! Now DSP uses pointers, and reserve memory as it's needed (I think it was when added PZX support). Thanks to Davide Michelini (and some forums) to point me to this bug.
I also fixed the sprites in Wardner.

09/03 - DSP Emulator 0.9b4 for Linux released. Remember this is a WIP version.

07/03 - DSP Emulator 0.9b4 Released. This final release added TMS-32010 CPU, and one of my favorites arcades Wardner.

01/03 - Added more M680X opcodes, added drivers for: Spelunker, Spelunker II, Lode Runner, Lode Runner II and Knuckle Joe. Fixed some small bugs.

This is the last week of WIP, this weekend the final relase of beta 4.

And now some coding tips: Some days ago reading some forums, I read that DSP consumes so much virtual memory, and testing much deeper I get a surprise... DSP reserves 1,5Gb of virtual RAM! (but doesn't uses it). I compiled DSP with Delphi 2010 and... the same problem! I tested a 'hello world' program and... the same occurs! It's incledible! Delphi reserves a huge virtual memory space without use! This is a Delphi bug, because compiling DSP with Lazarus everything it's OK. I will do more testing, but any help about this is wellcome.

23/02 - Fixed some bugs on M6800 CPU, added ADPCM to KungFu Master (sound it's more clean now)

22/02 - Added M6800 CPU series, so KungFu Master have sound (only missing ADPCM)

15/02 - Saboten Bombers: working 100% only missing sound. Added Bomb Jack Twin, added New Rally X. Added sound and controls to Snow Bros. Fixed sprites and background in Toki. Started the rewrite of M68000 core.

Fixed Rygar sprites and Psychic 5 initial screen. Fixed and added some opcodes on Motorola 68000. Added Hard Head 2 and Saboten Bombers drivers.

04/02 - Added DAC to HardHead and fixed bugs in Windows and Linux

03/02 - Download added: Linux binary (tested on Fedora 11 and Ubuntu 9.04)

02/02 - Hard Head driver finished, only remains DAC

01/02 - Xain'd Sleena driver finished, works 99% only remains a very small sprites glitch. Suna driver started, Hard Head begin to work, but missing sound and correct video emulation.

29/01 - Added basic driver for Xain'd Sleena with sound. Sprites, backgrounds and colors are missing

28/01 - These days I'm having some troubles with the IO's of Galaga (reaches the main screen, but goes crazy with coin insertion), so I shall change the driver to see if I clear my mind a little, and then return to it. I'll start with the driver of Suna 8 bits (Hard Head and Hard Head 2) and the Xain'd Sleena driver. And between all this I will review the drivers posted by Francenm some months ago, Sauro, System1 and Warp-Warp.
