About the ORT conversion, I made a quick and dirty program to convert from ORT to TAP, which could then be converted to WAV with wav2tap. I have to get to my PC for the code, but it was a quick hack and I know it has bugs, but it worked for my needs back then. As soon as I can, I may post it here. F...

About Twiligthe... it was a devastating loss. I just cannot imagine all the wonders that could have come out from his talented mind if he were still here...

He will always be missed.

Something similar was done in Oricium, with the difference that it was designed to draw pictures a sets of tiles (characters) not emulating a graphic mode for drawing primitives. Sprites were drawn on specific sets of characters. There were 40 lines of HIRES at the top, for the Logo/scoreboard, then...

Dbug's suggestion is sound. It would be the best way to test, as the ROM contents would be in a file in the disk and would be loaded into overlay RAM. Exactly as the SEDORIC tool to put Oric-1 or Oric Atmos ROM in overlay RAM.

EDIT: Moved the topic from General

Indeed. Fascinating times

I am quite sure that you can use the virtual tape (was that the name?) on Oricutron. I think that is what is used when the ROM is not the 1.1, and thus is not patched to load the data immediately from a PC file. Some turbo loading routines already exist and some games use them. With Oricutron, this ...

Hey Magoric! You finally decided to register here!

You'll see this is THE forum for all things Oric. Welcome!

Welcome!

Does this mean that Cumana Reborn has the Microdisc eprom instead of the Cumana's? Because IIRC they were hardware compatible... (they must be, or most games would not work!).

This is great iss! Thank you so much!

You caught my attention... why can't Cumana Reborn run CumanaDOS? Can a normal Microdisc run CumanaDOS or does it need something specific in the controller EPROM?

Really cool!

Here is the info about the dsk formats: https://wiki.defence-force.org/doku.php?id=oric:hardware:dsk_disk_format Our dsk format is not that different from others, such as Amstrad edsk (http://www.cpcwiki.eu/index.php/Format:DSK_disk_image_file_format) which is supported natively by flash floppy and ...

Probably the "old" format refers to one used in the early days with Euphoric. The image was just the byte content of the file, with no information of the mfm encoding. This was easy and compact, but I guess it failed to reproduce some disks, so the "new" mfm image appeared. This is then format we us...

I think there is no conversion from HFE to Oric dsk (yet). That is quite a pity, indeed. There are conversion for other similar formats, like Amstrad dsk/edsk format is supported, and it is quite similar. Maybe it could be possible to either create a conversion tool between CPC dsk and Oric dsk or t...

Ah, I'm too late to this thread, and iss has already answered perfectly

If you want to save 1 more byte you may change your jmp for a bvs. Be careful, though, as if there is a page crossing you will lose 1 machine cycle.
