Retro Replay
From ReplayResources
Original Specs available at jschoenfeld.com
For C64 and C128
PAL and NTSC models
This clone of the legendary Action Replay cartridge has been developed together with members of the active C64 scene. Technical data in detail:
- the read $de00 bug has been fixed
- the freeze-logik has been re-developed "from scratch" to be more secure than before
- The buttons are of higher quality than those of the original-AR
- the Freeze-key is digitally softened (no lockup on freeze)
- Software-switchable IO-area, so a REU can be used at the same time
- FlashROM programmable from plain C64
- Two different ROMs selectedable with a jumper
- 32K RAM and 128K ROM
- Original standard C64 cartridge size (shipped without case/shell)
- Expansionport on the cartridge allows conneting the SilverSurfer and the RR-NET
- Gold plated contacts.
- Mainboard in cool black (later revisions feature different colors). The iReplay with different skins might even become a market.
Known Problems
- Contact Problems: contact problems are the one major reason for strange behavior observed with the retro replay. before even suspecting anything else, ensure to have proper contact :)
- The retro replay itself has gold plated contacts, many if not most c64s however have tin, brass or other cheap metal contacts at the expansion port. This results in increased oxidation at the contacts (an effect well known in electrochemistry).
- the cartridge board is 0,2mm thinner than it should be
Fixing:
- clean the contacts of both the cartridge and the expansion port. you can use a rubber, or sand paper for that.
- bend the contacts of the expansion port so the cart fits more tightly.
- put some solder onto the contacts of the retro replay itself, which makes them thicker and also "softer" - resulting in better contact.
