Indeed SMSQ/E will automatically convert any mode SPR into the current Native High mode, so there is no reason to include all of them.dilwyn wrote: IIRC, there is a degree of automatic conversion when printing sprites in the high colour modes in GD2. So mode 32 and 33 sprites should work OK either way around. Can't remember for sure about 256 colour sprites, although I *think* they also display OK in mode 32 and 33. Same applies to the mode 64 sprites, although no mode 64 display hardware exists yet AFAIK.
When running in mode 4 or 8 High modes are not converted so these Low modes may need to be chained.
SQRview can load many QL & PC formats and these can be saved as PIC, this can then be converted to SPRs too.

There is also a version of Wolfgang's Chain program, wrapped in a PE interface that can handle Extended & Dynamic SPRs.

On the same page you'll also find my version of Per's Msprv/Sprv viewer which can better deal with big SPRs.
