sirlynxalot Posted January 23, 2022 Share Posted January 23, 2022 (edited) You can now buy completely newly built main boards minus a handful of components that do not currently have a modern day counterpart and are still required to be sourced from old gamegears https://retrogearcustoms.com/reviews/syf-sega-game-gear-mainboard/ How viable would this be for the Lynx?

I assume that it would be possible to create a single chip with 64k RAM plus Mikey and Suzy logic. Analogue with its Lynx cart adapter is pretty close.

+jgkspsx Posted January 23, 2022 Share Posted January 23, 2022 The Game Gear motherboard still uses the Sega custom silicon. There are a lot of dead Game Gears with salvageable custom chips. Lynx is not so lucky, either in quantity or likelihood of chips surviving a serious issue. I think an FPGA solution is probably the best we can hope for unless somebody wins a lottery. 2 Quote Link to comment Share on other sites More sharing options...
Songbird Posted January 23, 2022 Share Posted January 23, 2022 This is something I've wanted to do (either new silicon or FPGA core) for the Lynx for 10+ years. Did some cursory inquiries on custom engineering and PCBA build-out but of course it's a complex and expensive venture, so I never made it very far. 2 1 Quote Link to comment Share on other sites More sharing options...

There seems to be lots of guys creating verilog implementations of 6502. GitHub - Arlet/verilog-65C02-fsm In a way the design becomes easier when you also use RAM blocks inside the chip. A lot of nasty race-states go away with syncronous RAM. The moderng FPGA's also have dual port RAM blocks allowing Suzy and the CPU to write in the same RAM. Some day we will have the Lynx hardware defined in FPGA. But for the present I am waiting for my Analogue 1 Quote Link to comment Share on other sites More sharing options...
sirlynxalot Posted February 27, 2022 Author Share Posted February 27, 2022 (edited) I just heard about this, a board to hold a raspberry pi and line up with the controls and other aspects of the game gear case. Another intriguing idea that could also be applied to the lynx one day. www.hackster.io/news/drop-in-zega-mame-gear-ii-board-upgrades-your-classic-sega-game-gear-with-a-raspberry-pi-cm4-9d7b4a40a86b.amp Although this description says it's coming soon, I understand it's already available now and people have successfully used it.

+jgkspsx Posted February 28, 2022 Share Posted February 28, 2022 That is a neat project, but until somebody starts injection molding Lynx shells I really hope nobody does it to the Lynx. 1 Quote Link to comment Share on other sites More sharing options...
sirlynxalot Posted February 28, 2022 Author Share Posted February 28, 2022 (edited) I wouldn't want people to destroy working lynxes but aren't there already many lynxes that are damaged beyond repair due to getting a voltage spike to the proprietary Mikey and Suzy components, and unfortunately that will probably continue to grow overtime as casual people play lynx without realizing that the voltage regulating zener diode has failed from age?

Only reason to get an Analogue (in my world). 1 Quote Link to comment Share on other sites More sharing options...

The adapter was the only reason I ordered one. No confirmed date for the adapter yet afaik. 1 Quote Link to comment Share on other sites More sharing options...

The ONLY reason I ordered. Hopefully they'll follow through or I will cancel or sell it. Don't need the other formats. 2 Quote Link to comment Share on other sites More sharing options...
