| This hack add config menu options for random encounters. There are two hacks. the first one was version 1.0 which had an on/off option. The second one has 4 options respectively 0%, 50%, 100% and 150% random encounter rates. In other words, if you select 150% for example a random battle will occur in average 50% faster than normal. Both hack use free SRAM $7E1E1F to save the player's choice but this can be changed in main.asm.\\ | This hack add config menu options for random encounters. There are two hacks.

In other words, if you select 150% for example a random battle will occur in average 50% faster than normal. There is also a third option which is the multi options hack but it use Divergent Paths random encounters incrementor values (75% of vanilla values), so you can expect with that one around 75% of the random encounters number compared to the original game. All the hacks use free SRAM $7E1E1F to save the player's choice but this can be changed for example in main.asm.\\ |

| With the on/off options hack, you can now use the Moogle Charm relic for something else, and the new code does no longer checks for that flag ($7E11DF bit 1) when preparing a possible random encounter. You can also now repurpose the "no encounter" item flag. | With the on/off options hack, you can now use the Moogle Charm relic for something else, and the new code does no longer checks for that flag ($7E11DF bit 1) when preparing a possible random encounter.

| The same apply to the multi options hack but on top of that the Charm Bangle is no longer useful so you can repurpose it in the same mannner if you use that hack. In the multi options hack, $7E1E1F is loaded instead of $7E11DF when preparing a random encounter.\\ | The same apply to the multi options hack but on top of that the Charm Bangle is no longer useful so you can repurpose it in the same mannner if you use that hack.

| The multi options hack also has the difference that it edit and reorder the 8 incrementors tables. If you want to fine tune the random encounter rate, it's the best place to do so. I believe some fine tuning could be possible there; the 50% (half) and 100% (normal) tables have been kept intact but the 150% one does a flat +50% of the 100% table, in the same manner than the difference between the 50% and 100% table in vanilla (the values are doubled).\\ | The multi options hack also has the difference that it edit and reorder the 8 incrementor tables in asm/multi/bank_C0_multi.asm.

| Both hacks use 186($BA) bytes of free space at $C3F091. The reason they use the same amount of space is semi-coincidental, the multi-option hack $C3 bank code/free space has been optimized but there's more to it than the on/off options hack, which remains the same as in the 1.0 release. For the $C0 bank, 17($11) bytes of free space are used by the on/off options hack and 9 bytes are used by the multi options hack. You can change those free space offsets in the ASM files by modifying the org instructions as long as the new offsets are in the same banks. To assemble the hack type an xkas 0.06 command such as "xkas main_multi.asm rom.smc" at the root of the asm/multi folder.\\ | The on/off options hack use 118 ($76) bytes of free space at $C3F091 and the multi options one use 186 bytes ($BA) bytes at the same offset.

| A final note; if you use one of the two hacks you'll need to restart a new game to have it work correctly, because the correct SRAM initialization is done at the beginning of the game. An alternative is to use bsnes+ debugger, load a game and before entering the main menu go to debugger -> memory editor, then type 7E1E1F and edit the value there to a value between 00 to 01 for the on/off options hack and 00 to 03 for the multi options hack.\\ | A final note; if you use one of the three hacks you'll need to restart a new game to have it work correctly, because the correct SRAM initialization is done at the beginning of the game.
