And I knew I forgot to do something during Xmas...

freemac · 09:24, 19 January 16

I just commited r004.8.1.1, the first stable version of r004.8

Gryzor · 11:39, 19 January 16

Changes?

None,
it is just a classic code refactoring to improve global performance (not Amstrad performance, but core performance...)

Gryzor · 14:13, 19 January 16

Ah ok, thanks man!

r005

It's r004.8.2 + TV mode in bottom of OSD, this TV mode is original signal output (50Hz)

I have no TV so in case of problems, do write me at renaudhelias at gmail dot com (I shall have some returns in next weeks)

btw I'm losing more and more website ressource access (from home and from work), but I shall be always accessible from email.

*PS : I bought a MiST-board "MIDI extension version", and CoreAmstrad didn't work on it, so I had it to my TODO-list. Only low-cost version seems running CoreAmstrad correctly for the moment. I bought also a SCART adapter (but still not have a TV to use it ^^')

Gryzor · 14:11, 05 February 16

If I recall from the atari-forum others have had issues with the MIDI version...

Thanks for the update!!!

Great!

This is one of my favorite games ever! Sadly the English version can't be completed, it crashed at the end. So I suggest to use the French version if you want to complete it. (Else you may think it's a problem with the Mist, but it's the bug in the English version).

r005.2 - Yamaha port A debug (keyboard) - problem of delay in latches => GPA intro "press F1 or F2" unlocked.

r005.3c8 - experimental version, running on MiST-board "MIDI version". RAM optimization.

garvalf · 11:50, 15 March 16

I own a MiST with midi (midi built-in from Lotharek), and I don't remember having problems with the Amstrad core...

Well to know.
I reproduced the bug (Tobi's bug) in a MIDI-version I just bought, another guy (from Spain) had this problem in a classic version. Some RAM were turning into "sleeping mode", and needed better RAM synchronization algorithm...
Here a version that I'll commit next week. It is a final version, not experimental : here I know why it does solve this sort of problem

r005.4 - two upperROM set : if you press space during reset_key ("page up" key), it does load *.fXX ROMs instead of *.eXX ROMs
*.eZZ still contains common lowerROM...

Personnaly I have :
- ParaDOSv1.2.f07
- BASIC1-1-french.f00
- MAXAM.e05
- PROTEXT.e06
- ParaDOSv1.2.e07
- BASIC1-1-french.e00
- OS6128-french.eZZ

So my CPC does boot with MAXAM and PROTEXT inserted, and if I press "space" key during pressing "page up" key, MAXAM and PROTEXT are removed, so I can then insert Asphalt game dsk and play it.

freemac · 12:58, 25 July 16

... dsk SK bit (a first try) ...

test/fdctest/fdctest/fdctest.dsk

Test works best on an 80 Track double sided disk with correct ready.

SK and other tests here.
