#pinball

18 posts17 participants0 posts today

Cool. After my productivity speedbump of last night, my Time Machine #pinball #disassembly project has moved forward. I now have a python script which exports the #ghidra program into an info file which a real 6800 disassembler reads to produce assembly which should actually be able to be reassembled into a final binary.

I'll use ghidra to continue analyzing the code, and when I'm ready to actually start writing my own patches, I'll do that outside of ghidra as though it were a source file.

Found this fun project:

A user called 𝐩𝐨𝐧𝐨𝐩𝟏 has detailed their project - a #3DPrinting virtual #pinball machine all powered by their #SteamDeck

Some details:

⚪ Uses a 16" uperfect portable monitor
⚪ All connected to a cheap arcade USB encoder from AliExpress.
⚪ Everything connected to jsaux dock. 1 USB is arcade buttons, 1 is haute board and 1 is monitor for power

Video of my progress to make a clock out of a pinball score reel.

This is an Adafruit ESP32 Feather V2 running uLisp code to cycle four relays driving 24v to the reel solenoids.

The whole thing is wonderfully clacky and mechanical.

Next to do is wiring the zero switches on the reels back to the ESP32 so I know what number the reels are at.

I've been working on another clone (as is oft my wont) the past couple weeks to maybe build upon, this one for Nintendo's Pinball for NES. Not going too badly so far. Physics is fun to play with after working on a Shadowgate clone (very much non-physics).

This is it.

One year and 7 months later Road Show is once again in one piece and playable. The first test games did not reveal major issues, start mode scoop switch is flaky and the left plunger lane wasn't perfectly aligned. Other than that we played several fun test rounds with it!

I had missed this game so much!

Haven't worked on my #Pinball code #disassembly much directly, but I have been working to get all the tools I need collected. It seems like once I've used #Ghidra to annotate and explore the code I'll want to bring the disassembled "source" into a real editor to actually make my changes.

To ensure the actual disassembly is compatible with assembling back to EPROM images, I plan to write a script to convert ghidra's code representation into a file that will drive a dedicated 68xx disassembler

@SecretAntelope Actually now that I got thinking about it, we have a board game about pinball, a pinball machine about a board game but have you ever seen a pinball machine about pinball?

It's called Pinball and it was made by Stern in '77.

The honorable mention goes to Bally's Silverball mania, which in addition to also being about pinball, features family-friendly themes such as having sex with a pinball machine, right in the backglass.
