Amstrad CPC Core

[catenaccio]

Thank you for your config guys, I have tried both of them and still same issue. I will try other things ( periphericals and other devices) and will let you know with my findings

it is working now! just changed to crtc type 1, saved and reboot the system, and it is working fine

Could you try same game with crtc type 0 ?

Ty guys!

HI!

Missing sound for some games(when we move the character) like Boulder Dash, Jet Boot Jack for example.

I use the release 20190923.

Do you have any clue ???

@Sorgelig
it's really annoying. => ok i'm sorry don't be rude please....I'm just a little user you know...
By the way, thank you for the hard work. => you forgot this line i think.

I try to help, but you refuse my help.
I'm not complaining. You read it wrong.

Peace Man !

[Sorgelig]

it's really annoying.

Then you have to fix it finally!
I don't understand to who you are complaining for things you got for free.

[Titofff1970]

I'm sorry about how i feel, but why are you angry like that ???

It's just a feeling but nothing about you.

I respect totally your work on MiSTer, so why you talking like that ?

i don't understand really.

[Sorgelig]

Should be fixed in new release.

[Titofff1970]

Thanks a lot.

Work great with last release !

Tested on Boulder dash & Jet Boot Jack.

great work !!!

30 years megademo work

and DIRECT RECORDING tzx blocks are implemented and works

@gyurco the demo (the one with RUBI_DISK SYSTEM (c) 1990 MUSICAL LOADER BY RUB) doesn't work and we can't make cat (read failed)

I think I tried this one:

Ok, not on MiSTer, but it's the same FDC. Just turn off fast disk access, and start with |CPM.

[breiztiger]

yes but the other is different, it have sound loader and other disk sector map

CAT must work, i think it's the second sector that is abnormal size 1 in toc sectors

i always test with stock 6128 fr like my real cpc

why right shift on kayboard doesn't work in this core ?

i use a microsoft wireless keyboard

Ah, it just comes down to the fact that there are a C1h and a 41h sector id at track 0, and what the DOS sees first, determines what disk format it assumes. This one fixes CAT for this disk:
https://github.com/gyurco/Amstrad_MiST/ ... 5443013d08

I'm not sure if it cannot happen with real hardware if the disk is positioned at the 41h sector when it's checked.

[breiztiger]

but why when you start the core and load disk it's on this second sector ?

it doesn't appear on real hardware i think

That was just a coincidence. There's no real spinning disk, the spinning is simulated.
On real hardware it can happen, I think. Maybe only 1 out 100 cases.

seek track instruction doesn't make the drive read the first sector of that track ?

[slingshot]

seek track instruction doesn't make the drive read the first sector of that track ?

Seek is just seek, then another command is issued to read the ID, which reads from where the head currently is. The other part depends on this semi-random order, because it always reads sector id "1", which in reality different physical sectors on the other tracks on that disk.

[breiztiger]

i think your fix ins't necessary and relevant

i found a trick to launch this disc

insert another data disk and type cat

reinsert the demo and cat work

type ùcpm and the demo start ... but very very slowly (timer from music part loader isn't accurate)

fdc timing seem to be broken

[slingshot]

|CPM will start the demo, even CAT doesn't work.
It's the spinning simulation which makes the demo loading slow, as it's always reads sector ID 1, and all sectors have ID 1, it just reads what it founds under the head. If the simulation doesn't match what the demo expects (or what happens with the real disk), it's trying again. And refinig this simulation just for one demo is not really interesting for me (as it passes several copy protections, I think it's not that bad either).

Does addimg Plus range freature intrest you by any chace? There is a pretty amazing new homebrew port of Sonic in the works.

Plus is like completely different computer. It's not like just small addition.

[Sorgelig]

If there are patched versions without removing anything, then non-working original disks with protection is considered a minor issue.

[breiztiger]

Or fdc bugs
