Question Cdtv os 2.35

Has anyone any experience with the below and how does this compare to the improvements that Hyperion have done?

https://cdtvland.com/os235/

From their page:
Support for systems with 68030 CPUs
Support for systems with 32-bit Fast RAM
Memory card support restored for CDTV players
CD+G functionality restored for CDTV players
Buffer overflow bug fixed in bookmark.device
CD-ROMs will now boot even without CDTV.tm file
Ability to access the CDTV title screen when a harddisk is installed
Option to force exit CDTV title screen
OS build target device ID on CDTV title screen
No error screen when no disk drive connected to CDTV player

Honestly, reading the linked page, it sounds like the whole Cloanto vs Hyperion vs everyone else legal battle is the only thing that's really preventing (most of) this work from being integrated into OS 3.2+. (If I'm wrong and there are other legal issues preventing the work from being added, I'll be sad.)

It might even be that this will already integrate with the great work done with 3.1.4 and 3.2+ but it would be up to C4ptFuture to say so.

The boot any disk feature looks interesting:

He is speaking to the wrong company. Hyperion have an exclusive licence so there is no point asking Cloanto for permission, as they have no right to give such permission.

Definitely worth doing - they are better than the originals so I will be keeping them in now

Cloanto are the legal copyright holders for Amiga OS 3.x for 680x0 Amiga's including the CDTV Extended ROMs this is based on.

Hyperion released a version of the CDTV extended ROM with AmigaOS 3.2. We analysed it. They made no improvements. It's the original CBM 2.30 version for the A570 (now owned by Cloanto) byte for byte but with the version number changed with hexedit. Very illegal.

They misled people about the origins of the new Extended ROM in the release documentation implying it had been recompiled from sources. They misled people about the state of the extended ROM source code they have access to. They misled people about the nature of the bugs in the Extended ROM.

I like the Amiga OS 3.2 developers but whoever is producing this are using underhanded practices.

Best to just stay away from it and release binary patches.

That does not mean they can licence it out when they have already given an *exclusive* licence to another company.

I don't understand. Who licence what? Amiga Inc couldn't give a licence to Cloanto because they had given an exclusive license to Hyperion?

From what I know (and I'm no expert) Cloanto's original licence for existing AmigaOS 3.x binaries dates to 1997 and so predates any licences Amiga inc later agreed with Hyperion to exclusively develop AmigaOS 4.x which were made in 2001

You can read all about it in the court documents

Problem is, the IP holder contends that Hyperion *do not* have a license and is suing them. I'm not a lawyer either, but I don't think that -while this situation is unresolved- it is in my best interest to ignore the IP holder and approach the licensee to publish my work.

I'm not happy with the situation either, as most Amiga users probably, because it's a fucking energy drain to work around it, but I simply try to approach it pragmatically without emotion or fanboyism.

Anyone who wants to use v2.3.5 with Amiga Forever, note that the file you want to apply the patch to is actually amiga-os-130-a570-ext.rom, NOT amiga-os-230-cdtv-ext.rom.

@CaptFuture

In my view, you have done well in asking the IP holder and not the licensee, because as you said they are currently litigating in the US court. That license may or may not be confirmed, let alone Cloanto have had an earlier license since the 1990s.

Beside that and importantly, many many thanks to you and all involved for developing the patch for the 2.35.

It works great on my CDTVs (one with witcher, another with the SCSI adapter/ACE2/8MB fast ram).

It is good to see some love for the CDTV and a gift to the community.

The developer is really nice too and is open to suggestions for future versions, he even produced a file (In the Zone called cdtvstop)which allows you to boot games such as Dread without having to switch off the CD manually

I created the "CDTV Extended-ROM v2.35 (2021)(CDTV Land)(CDTV)" rom as per the instructions using bspatch, however when trying to split this rom into even and odd modules using ROMsplit I get the following error. Anyone else have this problem?

You cannot use ROMsplit with a custom (extended) Kickstart ROM like 2.35 because ROMsplit is dumb. It needs a config file for a particular ROM.

You don't need ROMsplit, just cut the file in two equal parts.

What tool would you recommend to do so?

The program should produce 3 files - ODD, EVEN and a single combined file for use in WinUAE:
How to apply the patch
Using Docker image
Requirements:

Intel based macOS or Linux operating system
Make
Docker
The official CDTV 2.30 Extended ROM image (md5 sum: d98112f18792ee3714df16a6eb421b89)
Steps:

Place the official 2.30 ROM in the root of this project directory
Rename it to 230.rom
Run the following command
make cdtvos235rom
You can also run the docker command directly if you prefer:

docker run --rm -v $(pwd):/data captainfuture/cdtvos235patch:1.0.1 /appl/run.sh
If the patch was succesful, you will end up with three new files in the current directory:

Filename Description
CDTV Extended-ROM v2.35 (2021)(CDTV Land)(CDTV).rom This is the 2.35 ROM image you can use in emulators
CDTV_v2_35_U34_Even.bin this is the split "even" binary of the 2.35 ROM image that you can use to burn to an 27c000 EPROM
CDTV_v2_35_U35_Odd.bin this is the split "odd" binary of the 2.35 ROM image that you can use to burn to an 27c000 EPROM

I know using Linux does all this for you but I used bspatch on Windows since I don't use Linux to create the new rom. It only created the new rom file and not the two Odd and Even files.

Docker is available for Windows as well, but honestly to simply set up the ROM and the split binaries having a requirement on it is just too much.

Hi,
I don't use Linux - I downloaded a Virtualbox image and then set it up from there - no easy task though as each time i put something in I had to look on youtube and forums to sort the problem - 8 hours later and it finally worked
