Re: The TF536 on a CDTV

I've dug a little deeper into some issues @8 Bit Dreams reported.

Looks like there are more AllocMem()'s in the boot loader code. I'll have to find them and patch them.

Is here a standard format for distributing Amiga Binary Patches? Fogive my ignorance as i really dislike patching binaries.

Re: The TF536 on a CDTV

Its completely tied to the ROM. IMHO you should update the ROM rather than patch on the fly. I can give out a binary patch list for both ROM types eventually.

Re: The TF536 on a CDTV

Yup,

That works. Please donate to WinUAE if you were looking for TF support on the CDTV.

I tried patching cdtv.device... no joy. However I did exchange some emails with Toni Willen and he suggested patching cdfs.device CODE:000031BC ; =============== S U B R O U T I N E ======================================= CODE:000031BC CODE:000031BC CODE:000031BC sub_31BC: ; CODE XREF: sub_7A0+6A↑p ...

Re: TF536 on the ST

Nobody has solved the re locator issue yet. Some ST models its probably possible due the CPU location being seemingly random on the ST motherboards :)

Re: exxos 534 blog - Atari

Ah i would expect GB6 to alloc some fast ram, copy the routines over to fastram, run em there and get some numbers.

EDIT: or rather thats how i'd expect meaningful results to be obtained.

Re: exxos 534 blog - Atari

Thats a pretty low score for fastram. The Amiga 2000 and CDTV rate the 534 at around 16mips when running in fastrom.

Does the ST turn on the CPU caches/burst mode?

I have made a lots of testing with burned CDs with CDTV. I have tested at least 4 different CD burners and burned CDs only works IF you burn them max 5x speed. Burning CDs with 32x wount work. There is no sensible explanation for this, I know.
I burned my CDs at 1x speed.

Re: The TF536 on a CDTV

Generally would prefer no patching in firmware. But if it’s a single byte then I could do a man in the middle stunt and only patch if the rom read as $2700. That would be safe on all machines and you could decode all the mirrors.

Re: The TF536 on a CDTV

Will this subroutine be called each time CD is thrown in? I guess we can find out by testing a CDTV in WinUAE with that as a breakpoint. Can You redirect it on the fly? We can also patch cdtv.device in extended rom in worst case... Patching a single ROM location is easy but i have a suspicion that ...
