SkillGrid receives one more update, which not only makes is slicker than ever, but also adds a new bonus cell - BEAM/ULTRA - which increases the shapeship firepower so that even the nastier boss can be faced with utmost confidence.
Moreover, Amiga CD³² users can now enable the hiscore loading/saving from/to NVRAM (see readme.txt on the CD).

(If you downloaded the files yesterday May 21st, 2022, please re-download them as they contained some not-fully-updated documentation files.)

v1.3 (21.5.2022)
1. Added the BEAM/ULTRA cell (shoots a big beam that is equivalent to 5 beams).
2. Moved the lateral beams of the triple beam one pixel down (to match the shape of the ultra beam).
3. Reduced by 16.7% the occurrences of the DAMAGE cell.
4. Worked on the music playback:
· optimized the decoding;
· optimized the handling of the state;
· removed the pairing of channels on the same side (which caused the title and game over screens music to play louder than the in-game music - an originally intended effect which I have changed my mind about - and did not really work for channel 3 as that channel cannot sustain 28836.5 Hz).
5. Slightly improved the standard music quality by re-downsampling the data after improving the amplification.
6. Changed the keyboard handling so that it executes from a level 3 interrupt handler instead of a level 2 interrupt handler, in order to work around issues/lockups caused by expansion hardware sending INT2 interrupt requests.
7. Replaced [SPACE] with [LEFT ALT] and [RIGHT ALT] as [FIRE] button.
8. Made the startup procedure more robust (especially against audio playback performed with direct hardware access by other programs concurrently).
9. Made various little optimizations.
10. Added the possibility of enabling the loading/saving of the hiscore from/to the NVRAM in the Amiga CD³² bootable version - EXPERIMENTAL FEATURE: CHECK OUT THE README ON THE CD FIRST!
11. Worked on cells graphics:
· fixed colors of beams on BEAM/DOUBLE and BEAM/TRIPLE cells;
· fixed a pixel on the border of the ASTEROIDS, BEAM/DOUBLE and BEAM/TRIPLE cells.
12. Worked on manual and stragegy guide:
· renamed DOUBLE BEAM and TRIPLE BEAM as BEAMS/DOUBLE and BEAMS/TRIPLE, respectively;
· added the information for the BEAMS/ULTRA cell;
· adapted the information for the other BEAMS/* cells;
· added the BEAMS paragraph;
· updated the ASTEROIDS, BEAM/DOUBLE and BEAM/TRIPLE cells images;
· updated the CONTROLS table;
· fixed the outer antialiasing of the BEAM/TRIPLE, BOOST and BRAKE cells images;
· fixed the kerning of the last character of the italic strings.
13. Set the default tool of the manual and strategy guide icons to "Apdf".
14. Updated the artwork to reflect the new beams graphics.
