The workaround for address independent code (assuming the source code is available) is for an address translation program to run before jumping to the game/application code.

The non-use (or restoring the correct value) of certain Z80 registers only becomes a problem if you want to use the built in ROM routines or return to BASIC. It’s not needed if neither of these happens.

The bigger problem is the very different input and output I/O hardware….

Applications / Re: Git proxy for CPC?

I downloaded the M4 rom node code available in the unidos site. There is code for the FTP support in it but not enabled to assemble by default.
Yes, it was just some preliminary FTP test code.
Not really usefull for the end users yet.

Current (unreleased, waiting for final fixes) version contains the full featured FTP implemenation.

Amstrad CPC hardware / Re: Tecnobytes V9990 New Batch
« Last post by TotO on Today at 00:27 »
Yes but the idea of this thread is (probably now was) to get enough people together to order a batch of a card that exists... But that's been derailed. Seems the objective is to stop people ordering this real piece of hardware for an idea you have in your head.
I really doubt about that, because the poll has grown after the post to explain my choice. I have no doubt that people can choose for themselves according to their desires and uses, because the V9990 is a great Yamaha VDP, close to the Mega Drive one, but for 8-bit systems.

EDIT: Looking the poll again, you have reach the number required (22+3) and you just have to wait them to pay.
I'm pretty sure that some other people will ask for the expansion late (hurry up!), because "avaliable".

Amstrad CPC hardware / Re: Tecnobytes V9990 New Batch

This is another thing. I talked about the fact that using the V99x8 was compatible with SymbOS and offered the possibility of porting existing MSX games to the CPC. this was not directly related to the ability to display everything on the same screen, but is more relevant for the V9990.

I know all of these things, I saw this on the internet and at the Revision event with you. Just because I would like the V9990 card to be different doesn't mean my post is negative. I explain a point of view, that's all. Something that seems to be difficult to have for 5 years with all these social networks that only allow you to say "like" and no longer to think differently or exchange opinions without being classified or upset people.

Do you think, that superimposing or signal passtrough is more easy for the 9938 compared to the 9990? Both require additional hardware to do this. I am not a hardware guy at all, so I have no idea.

But when you have a look at the Philips 8280 it's already a lot of stuff. AFAIK the 9938 can't do this without any extra hardware. So I wonder what's the issue with the 9990 compared to the 9938 regarding this?

For the V9990 it looks similiar with the Video 9000, which does superimpose as well.

Another question is:
Since the V9990 has been connected successfully to the CPC for the first time, already 4 years passed.

It is available since 4 years, fully working, and we made new software for it and can use all existing ones for SymbOS as well, so you already have a lot of 16 colour stuff on the CPC running at very high screen resolutions.
But nobody else created another video hardware during this time. Why should this happen right now?
There are probably other graphic chips, which are fine as well. From my side, it would be very easy and really cool to port and use the VDP9938 MSX screen driver to SymbOS CPC as well, if someone would build such a hardware.

But if such hardware is not available, and no one is planning to do something within a realistic time frame, it doesn't make sense to say, that the G9K is not a good solution, except you want to talk in a negative way about a current project, which already exists. But this wouldn't be nice.

The main reason for using the G9K as a new standard video card for the CPC/MSX/Enterprise (maybe even PCW in the future) regarding platform independant fullscreen games is, that's it's probably the most powerful and easy to program video card which has ever been developed for an 8bit system.

Technical Support / Re: Can I convert a PCW disc to a CPC format?
« Last post by GeoffB17 on Yesterday at 23:21 »
Prob YES.

The files on my disk would work that way.   HITCHHIK.COM would run as you say.   But if you needed the CP/M 2 version, or the CPC version, then copy HIKER2.COM to HITCHHIK.COM, or just run HIKER2 instead of HITCHHIK, and you're in the right place.

I could confirm the screen codes in HIKER2 if that would help - I'm guessing that they may be right for the CPC?

Hm, why so negative about a new V9990 batch and the current developments?  :(
Hey, it is not negative but objective. I had prefered this VDP expansion with a video signal passthrough to display all on the CPC monitor by using /YS and a multiplexer IC. I understand that is nice for SymbOS, but I don't see any interrest except that. (much more by using V99x8)

If they will send this from Greece to Australia and then back from Australia to Greece, maybe this is the first Amstrad Tape which orbits the whole Planet Earth within a few weeks  ;D (in less than 80 days?  :D )
