Some errors in displaying sprites/extra .png in sprite path

When playing the game through this section (see below), it says "bmp\zoom\gap_akuwaraiA1az20.png.png" can't be found in the error log

```

;ld c,$GAP_akuwaraiA4,80
lsp_var 1,"bmp\zoom\gap_akuwaraiA4az20.png",-73,0
print 80
```

specifically it's the lines like:
`lsp_var 1,"bmp\zoom\gap_akuwaraiA1az20.png",-73,0`

Should also check the rest of the script if the lsp_var function is called elsewhere with `.png`, so it can be fixed

There is also an error for the textbox. The full error is below:

```
*** can't find file [textbox\clean\.png] ***
*** can't find file [big\bmp\zoom\gap_akuwaraiA4az20.png.png] ***
*** can't find file [big\bmp\zoom\gap_akuwaraiA4az20.png.png] ***
```

El issue señala errores de carga de sprites en líneas de script que usan lsp_var con extensiones .png duplicadas. Busca en la base de código las llamadas a 'lsp_var' para encontrar todas las ocurrencias. Verifica las rutas de archivo y la lógica de carga de sprites para asegurar extensiones correctas. Verifica la corrección ejecutando el juego y revisando el registro de errores en busca de mensajes de archivos faltantes.
