This is an important point - I have an internal scandoubler in my Amiga, but my LCD doesn't sync down to 50Hz so it doesn't display anything at all. It goes down to 56Hz but it isn't enough.
I suspect Roy's scandoubler is the same - it won't make a PAL machine display on an LCD that doesn't vertical sync down to 50Hz.

Well.. time to release some info on my forthcoming unit:
- A1200 internal, plugs over Lisa, no other chip-connections (other internal flickerfixers used an additional Alice-adapter)
- might fit in A4000T, but will not fit in A4000D or CD32.
- full 24 bit colour depth for all screenmodes and output frequencies
- all OCS/ECS/AGA screenmodes displayed and scan-converted, output is always over 60Hz and flicker-free
- fallback to legacy flickerfixer-type 49,9Hz modes at the user's choice
- optional scanline emulation for retro-feeling
- re-configurable design, new screenmodes can be added with a software upgrade
- Genlock compatible (Toaster/Flyer)
- no fiddling with adjustments, just plug in and use
- low power consumption, no heat problems (3.3V design, 2.5V core voltage)

Versions for A4000D and OCS/ECS Amigas coming up when the A1200 version started selling and some money is made back.
This flickerfixer breaks three rules in one product:
- 16 bit is not the limit in colour depth
- 50Hz is not a "must" when flickerfixing PAL screens
- SHires can be perfectly displayed and flickerfixed
The design uses only up-to-date parts and is moving more than 300 Megabytes of data per second.
