### Mark Grebe

Thanks for creating SDLTRS!

### Tim Mann

SDLTRS would not be possible without wonderful TRS-80 emulator upon which it is based, xtrs. Thanks Tim!

### libSDL Team

Big thanks also go to the libSDL team for creating the great cross platform library that makes SDLTRS possible!

### I also thank the following people for their help:

- Alan Cox wrote the banked memory support, emulation of the Lowe LE18 graphics adapter and fixed a couple of nasty emulation bugs.
- The JV1 and JV3 floppy disk file formats were designed by Jeff Vavasour, originally for his MSDOS-based TRS-80 emulators.
- The DMK format was designed by David Keil for his MSDOS-based TRS-80 emulator.
- The hard disk file format was designed by Matthew Reed for his MSDOS- based TRS-80 emulators.
- Al Petrofsky and Todd P. Cromwell III supplied font data.
- Roland Gerlach contributed the CP/M import and export programs as well as several bug reports and fixes for the emulator itself.
- Ulrich Mueller added the `-borderwidth` option, improved the `-scale` option and the bitmap font scaling, ported the IMPORT, EXPORT, and SETTIME utilities to NEWDOS/80, and contributed the HRG1B emulation.
- Branden Robinson supplied the first version of the cassette man page, fixed Makefile bugs, translated cassette to the Bourne shell, and implemented watchpoints in zbx.
- Mark McDougall provided documentation for the Micro-Labs Grafyx Solution card.
- Jens Guenther added the `-title` option and contributed code to emulate the GENIE (German Model I clone).
- Joe Peterson contributed code to emulate the TimeDate80 and the `-emtsafe` feature.
- Denis Leconte contributed part of the `-scale` implementation.
- Felipe Sanches wrote the original CP-500 driver in 2017 for the MAME project to support the extra 2 KB EPROM (integrated Z80 monitor).
- Klaus Kaempf wrote the EG 3200 (Genie III) driver for the MAME project in 2020 which provided valuable information for the implementation.
- George Phillips provided documentation for the Anitek MegaMem card.
- Fritz Chwolka helped to improve the TCS Genie IIIs emulation by running some tests on a real machine.
- Leonardo Brondani Schenkel wrote the CP-500/M80 emulation for SDLTRS to run the CP/M 2.2-clone SO08 from Prologica.
