Ultimate 64 Firmware
Release v1.06 / v3.3Download
- U64_1.06.u64 (Facebook page)
- U64_1.06.u64 (local)
- SHA-265: cfb5beb3725ee2277abad2c4274ebcb89e2dd6cd
Gideon:
This is just a snapshot. No release notes etc… Many people were asking me to release this update, so here it is.
Changes- NEW: Audio Mixer
- SpeedDOS Parallel Cable (needs e.g. DolpinDOS roms)
- Interface type: Ultimate Menu picture overlay (HDMI-only)
- USB keyboard support. Like earlier firmware, press scroll/lock to enter/exit the Ultimate menu.
Note:
You will need a kernel, basic and character rom after the upgrade. These roms are not included in the update. These roms are distributed with vice-emu, but you can also find them on zimmermans.net.
For instance, you could use these roms: 901225-01.bin (char), 901226.bin (basic) and 901227-03.bin (kernal). Roms with the .rom extension should also work.- 4. Oktober 2018
FLASHING FIRMWARE:
Die neue Firmware darf sich in einem beliebigen Verzeichnis befinden und kann im Dateibrowser ausgewählt werden. Dann kann man die Flash Option wählen und diese schreiben. Nachdem erfolgreichen Flashen und Restart sind dann wie beschrieben die System ROMs einzubinden.Vorteil: Du kannst auf Deinen Stick alle Firmwareversionen drauf lassen - und bei Bedarf down- und upgraden. Praktisch, wenn man bei einer Inkompatibilität wissen will, ob die schon mit älteren Firmwareversionen bestand. Dazu passend: 1.00, 1.02 und 1.05/1.06 sind alle Firmwareversionen für den U64 (1.05 und 1.06 unterscheiden sich dermaßen minimal, dass es für die Kompatibität keinen Unterschied machen dürfte).
Die Empfehlung im Firmwareupdater, die Konfig zurückzusetzen, bezieht sich auf Benutzer, die von Firmware ≤ 1.02 kommen. Wer von 1.05 kommt, darf die Empfehlung ignorieren, es besteht dafür dann keine Notwendigkeit.
Eine Flash Anleitung für die System ROMs
Flashing System ROM
Before you can use your Ultimate 64, you have to flash your Kernal and Basic ROMto the Ultimate 64. Power on and wait for picture, where it explains how to do.
Basically you stick your USB drive in the back of the Ultimate 64 and push shortly on the power buttonto bring up the Menu.- Browse to your Kernal ROM image and press Enter.
- Choose Flash as Orig. Kernal ROM.
- Browse to your Basic ROM image and press Enter.
- Choose Flash as Orig. Basic ROM.
- Browse to your Character ROM image and press Enter.
- Choose Flash as Orig. Character ROM.
- Push F5 and choose Reboot C64.

Ich habe gerade eine neue inoffizielle Ultimate 64 Firmware 3.3a_181125+_v1 hochgeladen. Am einfachsten zu finden über den Releases-Link in meiner Signatur.
Änderungsliste s. o.- beim Updaten von Gideons Version 1.0B trift die von meiner erweiterten Version 3.3_180912+_v1 zu, beim Updaten von meiner 3.3_180912+_v1 sind Gideons Änderungen der 1.0B neu.
Die folgende Änderung hat Gideon beim Mergen deaktiviert, so dass die in dieser Version nicht enthalten ist:
Zitat von markusC64
* Wenn Sie beim Einschalten des Ultimate 64 die folgenden Tasten drücken, ändert sich der Videomodus auf
D => DVI
H => HDMI
R => RGB
C => Composite/S-VideoHintergrund: Dies soll eine möglichst stabile Version sein. Hier hat Gideon Bedenken, dass der C64 beim Einschalten einen Tastendruck irrtümlich erkennen könnte.
Edit: Sollte wer bei einer frisch gelieferten Ultimate 64 eine neuere Firmware als hier (d. h. in diesem Thread) angekündigt vorfinden, bitte um kurze Nachricht.

Firmware for the U64 / U64E, version 1.37 - Dated: 2020-12-05
Wichtig: In den Settings sind jetzt die Tasten '+' und '-' für die Einstellung von Werten notwendig - zum Beispiel die Gerätenummer der Floppies (8 bis 11).

This release has again some significant changes and improvements over 1.34 / 3.8. The following bullet list gives an overview of the features and fixes. Below the items, a short explanation is added.
- exFAT support
- Cartridge Port compatibility improvements
- Hyperspeed file system access through UCI
- Extended CBM file system support (D71, D81 and DNP)
- Full REL file support from SoftwareIEC
- REL file copy between file systems, including FAT with preservation of record length property.
- Consistent filename convention for storing CBM files on FAT with proper conversions.
- Free block count added to IEC directory listing.
- F5 menu restructuring
- Configuration menu key mapping made more consistent with file browser
- RAM Disk addition
- ACIA (6551 emulation) improvements
- Added fast serial / burst mode wire patches in U64 (optional connections between CIA and SRQ / DATA line.)
- Addition of additional analog video modes: PAL60 and NTSC50.
- Slightly improved key mapping for USB keyboards.
- Fixed double keypress in non-overlay menu, when using USB keyboard.
- Implemented key repeat for USB keyboards.
- Many, many bugfixes
exFAT support: Until earlier firmware versions, it was only possible to use FAT16/FAT32 formatted USB disks. Version 3.9 adds the support for the newer exFAT. Many, if not all newer USB sticks are factory formatted with this file system. This brings the maximum disk size to 2TB. Note that 64-bit LBA is not supported.
Hyperspeed file system access through UCI? What does this mean? It means that the virtual file system can now be accessed using a driver that talks to the Ultimate in I/O space, in a CBM compatible way. [UCI stands for Ultimate Command Interface] In order to unleash this hyperspeed, a customized C64 kernal is available. This kernal includes the driver to map one of the device IDs to the virtual file system of the Ultimate. Loading speeds in excess of 200+ blocks per second are feasible. As long as kernal calls are used to access the ‘drive’, this is fully compatible with existing software. Note that this kernal also supports the @ and $ commands, to give drive commands and show the directory of any drive, including the device-ID that routes to the UCI.
Extended CBM file system support means that all (D64, D71, D81 and DNP) images can now be created and are fully writable. Although there is no hardware emulation yet of the 1571 and 1581 drives, the support for the file systems is there. In combination with the hyperspeed kernal driver, this is already very useful, even without hardware emulation of the drives.
REL file support has been added, and in such a way that works regardless of the underlying file system. Thus, it does not matter if the REL file is located on a FAT filesystem, or inside of a CBM disk image. The way the REL file is stored is dependent on the file system, including the side sectors and super side sector for CBM systems. Copying REL files between these file systems is therefore also possible, and the side sectors are created as needed.
Block Access (U1, U2 and B-P commands) have been added. When the current directory is (inside) a CBM disk image, these block commands can be used to read / write random sectors of the disk.
A new file naming convention has been introduced, which makes lossless conversion between CBM and FAT filesystems possible, up to 16 chars. It may not always give pretty results, but it is consistent.
The F5 menu (Task Menu) had grown into an unorganized mess. This has now been restructured and categorized, so it has become a lot easier to find the item and is thus quicker to use. Similarly, the key mapping of the configuration menu has been made more consistent. The cursor keys now always navigate through the menus. Use '+' and '-' to change the value. (I have to get used to this myself!)
In addition to the support for USB disks, an additional RAM disk was added. This is very useful for storing temporary disk images, updater files and so on. It can also be used for an even better file system performance. The size of this temporary disk is 16 MB and does not conflict with REU memory. It is truly additional. In a future version, this temporary storage will be used to implement remote commands that require data to be uploaded, such that remote commands will be more consistent with actions from the file browser, since all actions will be based on the file system.
Cartridge port compatibility improvements. Since the introduction of the turbo mode, the cartridge compatibility of the U64 was flawed. This is simply due to the necessary changes in system architecture to make the turbo mode even possible. In this system core version (1.37), some of the compatibility issues have been solved. In particular, cartridges that toggle the EXROM# / GAME# lines per cycle or even during a cycle are now handled correctly again. This affects also the IDE64 module. In order to get this to work, the cartridge bus mode should be set to "Dynamic", which basically means that the U64 will carefully 'probe' the cycles on the cartridge bus to see how the cycle completes. By cleverly caching these results, turbo mode is applied automatically in memory regions that do not need to run at 1 MHz. This does not mean that cartridge compatibility is now guaranteed for all modules, but it is a good step.
The additional analog video modes can be used to run PAL software on analog monitors, such as the 1702, or run 60 Hz software on PAL only screens. In addition to this, the cyan color was adjusted in the analog signal, as it was too green.
The ACIA improvements fix the problem that occurs when an NMI interrupt is missed. In addition, the DCD and DSR lines can now generate interrupts, like on a real 6551. The modem emulation supports pulsing these lines when an incoming connection occurs.
The list of bugfixes is too long to describe here. Some of them were minor; others would eventually hang up the ultimate application; memory leaks… Many thanks to Bart van Leeuwen, who thoroughly tested repeated file system access through UCI.
