ZXPresh congratulations on achieving the impossible with such a highly technical game running on such a limited system.
Suggestions for the final release:
- The game name should be changed to simply reflect the original arcade title for the sake of accuracy and authenticity as it already infringes copyright. It would look much better to present it as Street Fighter II: The World Warrior with a well designed colour logo that avoids colour clash. The name change would be the most important suggestion.
- An MGT disk image version for DS/DD 3.5" 800K (720K formatted) disks as this would be suitable for the +D Disk System such as the PlusDLite.
For future revisions of the mass storage version of the game (non-tape version) may I suggest the following:
1. Kempston multi-button joypad support for Sega Master System (2-button), and Sega Mega Drive (6-button) controllers
2. Possible speech when SFX and music are not used such as "fight", "you win", "you lose", "round 1" etc.

This may require additional sound channels and could require the addition of a 6-channel AY TurboSound chip being present. TurboSound is fast becoming a common standard via add-on expansion for original hardware and built-in to clones like the Sizif-512 and ZX Next.
3. Add the arcade "continue" screen with the number counter and character portrait
4. Use the "Versus" screen before each level to display the fighter and opponent for that match
5. The inclusion of bonus levels and the points system
6. Include the world map and flight path to show the level progression for the player before each match
7. Include a mono "attract mode" screen showing the two fighters in front of the office tower block followed by character bio and stats
8. Include each characters win quote after each match
9. Each character has a different ending when the player completes the game.
Thank you.
