Is the Sidekick trying to snoop the bus and do interrupt the kernal to enter it's interface?
I ask because it seems very unfriendly to custom kernals.

Is the Sidekick trying to snoop the bus and do interrupt the kernal to enter it's interface?
no, it's functioning like a normal cartridge (via EXROM/GAME), it doesn't do any guesswork what's going on
which kernal are you using? -

which kernal are you using?I use either the regular Jiffy kernal, or the Jiffy-Dolphin kernal. I also modify it to skip the RAM test so it boots immediately.
I would say that is what the SideKick doesn't like, but I also modified the regular CBM v3 kernal this way and it does work with Sidekick.

I also often use the Jiffy-Dolphin kernal without any problems. SK64 simply pulls GAME and EXROM low and emulates a 16K Cartridge, $8000-$9FFF / $A000-$BFFF. Have you (manually) checked if the CBM80 signature is at $8000?
You didn't say what "SK64 being unfriendly" looks like

difference between a lcx07 and an lvc07
both are 5v-tolerant, the difference is the (range of) supply voltage(s)
Thank you for clarifying this. Very interesting.

r.cade are you able to post a copy of your custom kernal ROM's?
I can try it on my Sidekick64 cartridge to see if I can replicate this issue.

Sorry, when powered on, I just get a blank screen with borders instead of the SideKick interface.

hm, did you change anything else in addition to skipping the RAM test? (SK calls a few kernal routines during startup, did any addresses change?)

I will send them to you in PM to take a look. All I did was disable the RAM check on them.

I've tested your kernals on both PAL and NTSC (on a 250425) and I did not experience any problems. SK64 came up as it should... is there anything special about your C64?

I guess I need to test it on one of my others. Maybe there is some issue...

I believe on this C64, C24 was reduced to lower the boot/reset time also. It seems to be too much for some reason. I will put it back to stock 10uF or 22uF.

interesting! so this controls how long RESET is pulled? Have you measured how long it has been using your C24?

I'll take a look. I know I meddled with it years ago to try to get it as fast as possible. You don't know how much of my life as a kid was waiting for C64 bootup, and it was only seconds!

Has anyone managed to get the new Eye of The Beholder (https://csdb.dk/release/?id=226060) game running via the SideKick64 on a C128?
When I get to the start of the game where it offers the possibiliy to run it in 2Mhz it crashes before I can make a selection and goes to a blue screen.
-
Wow! Automap via VDC!

2MHz mode caused a crash for me but if I leave it off it runs for me but with some minor graphical glitches.
Frenetic already stated that he would have a look in the other thread regarding EofB.

Hallo Frenetic,
habe heute einen aktuellen SideKick64 (V0.42) gelötet.
Der SideKick kommt an einen 64er.
Der vorhandene Pi ist ein 3B+.
Jetzt würden mir folgende Antworten weiterhelfen:
- Ich habe ein "normales" C64 II Netzteil, ist ein zusätzliches Netzteil für den Pi ratsam?
- Welche Jumper sind wie zu setzen? Multiplexer Delay D=0 und "A13" oder "Btn"?
- Auf der Github Seite finde ich das Verzeichnis Source/Firmware, was muss alles auf die SD-Karte?
- Was habe ich für den ersten Betrieb zu beachten?
Danke!
-
was muss alles auf die SD-Karte
Frage in die Runde: wäre es im Prinzip ok, seine komplette sidekick SD für andere hier hochzuladen (oder in die Wolke)?
-

Ja, D=0 -- und A13
Auf der Github Seite finde ich das Verzeichnis Source/Firmware, was muss alles auf die SD-Karte?
auf die SD-Karte muss nur das, was Du unter "Release" (auf der rechten Seite oder hier: https://github.com/frntc/Sidekick64/releases/tag/v0.51) findest
Was habe ich für den ersten Betrieb zu beachten?
die ersten 100km etwas langsam machen
(= nichts)Ich habe ein "normales" C64 II Netzteil, ist ein zusätzliches Netzteil für den Pi ratsam?
Netzteile sind immer ein heikles Thema
ich habe einen Stromverbrauch gemessen, der innerhalb der Spezifikation des Expansionsports liegt. Allerdings sind die alten Netzteile ja auch nicht für Ihre Zuverlässigkeit bekannt, ich will Dir also lieber nicht zu etwas raten, was nach hinten losgehen kann. (ich selbst verwende kein originales NT). Bei zu knapper Stromversorgung läuft der RPi instabil -- das würdest Du entweder am Blitz-Symbol in der HDMI-Ausgabe sehen, oder einfach an einem nicht-funktionierenden SK64 merken... -
Hallo, ich habe eine Frage zu den TFT Display´s. Ich habe hier ein Pi 3b+, und die Sidekick64 v0.41. Verbaut ist ein TFT Display mit dem ST7789 Controller, welches allerdings dunkel bleibt. Die Lötbrücken sind richtig gesetzt, und die CFG Datei ist angepasst.
Mir ist aufgefallen, das etwas angezeigt wird, wenn ich den BLK-Pin auf VCC lege. Also grundlegend klappt alles, bis auf die Beleuchtung des Display´s. Ist vieleicht einem das "Problem" bekannt?
