Aktuelle Core für Commodore 64 12.01.2017

Hi Kris!

I tried to use new C64 core same way like C16.
To Commodore 16 I added to root directory c16.rom - Kernal with JiffyDOS and it works - JiffyDOS is available.
Commodore 64 core before this new could have any ROM in root directory and always ignored it.
New Commodore 64 core I used same way like C16 - I added to root directory c64.rom - but it hangs with clear screen - no text, only paper and border.
I used JiffyDOS 6.01, Japanese Kernal and original Kernal - each in correct size 8K = 8192 B.

But this core ignores not ROM named c64.rom - so, how to use custom ROM, maybe JiffyDOS or other?

Each idea is welcome.

Hi!

ROM file fixed, but not fully.

I was playing around ROMs and tried to add chargen and Basic.
So, after testing I got to work combination joined together into c64.rom:
Basic ROM + Kernal ROM + Character ROM
In this order I successfuly got to work JiffyDOS.
All works, JiffyDOS commands too - but - disk access hangs...

Any idea?

I tried the same with the same result. The screen turns blank... blue but blank... the menu appears after F12.

Nice idea to get Jiffydos running. hope it will work some day- - if so please inform how... thx!

Auf Facebook in der Gruppe "MIST FPGA Computer" liegt ein neuer C64 Core zu Download.
Er soll jetzt auch T64 Dateien laden können.

Ich weiss nicht ob ich den hier einfach so zu DL anbieten darf. Deshalb lass ich das jetzt besser.

Using JiffyDOS with C64 core:

create ROM file named c64.rom in this order:

Join together basic + kernal + 1541 ROM by copy /b
Basic - not yet tested other than 2.0 - req'd size: 8K
Kernal - JiffyDOS or other - req'd size: 8K
1541.ROM - JiffyDOS or other - req'd size: 16K

place c64.rom into root directory of SD card

If you want to use JiffiyDOS incl. faster R/W both Kernal and 1541.ROM must to be JiffyDOS.
or you can create custom machine, only one feature is missing for machine customize - chargen.

Hier ein neuer C64 Core vom Facebook Mitglied "Lee Ashmore" aus der MIST FPGA Computer Gruppe.
Er soll T64 Dateien lesen können.

Falls es mit der gezippten Datei Problem gibt, bitte melden.
Am Besten per PN.

Viel Spaß

Sorry wenn jetzt erst Antwort. Hatte viel um die Ohren die letzten Wochen.

Die Frage mit den Changelogs kann ich leider nicht beantworten.
Dazu hat der Programmierer leider nichts geschrieben.
