PC Engine DUO-R Console and 15 Games - Junk Item

Includes PC Engine DUO console, 15 software titles, 3 controllers, and a multitap.
The console and software are confirmed to be in working condition.
Salamander did not boot, so please consider it a bonus.
The standard controller worked fine.
The Hori Commander has a weak contact for the start button.
The genuine controller has a weak contact for button 1.
The AV output contact is a bit unstable; if the screen doesn't display, gently touching the cable should resolve it.
Data backed up in February remained for over two months without issues, so backups should be reliable.
The condition of the software is generally good, but the case for Sherlock Holmes is cracked, and the CD condition is not great.
The demo software's CD is clean, but the case is damaged. The CD for Tengai Makyou 2 also has some scratches and is not in the best condition.
There is a rubber-like melted substance on the back of the Nectaris case. See photos.
If you have concerns about the condition of other software, please comment, and I will provide additional photos.
Please comment if you wish to purchase without the software.
There are 6 bare software titles, and I have 3 software cases, so I will put two discs in each case.
As this is a game console that has not been maintained for over 30 years, it is being sold as a junk item.
No returns or complaints, please.
