+NOTE:
+The hotbubl set is also known to use double sized EPROMs with the identical halves:
+ Program data on a 27C020 EPROM:
+ ROM @ C1 with a CRC32 of 0x7bb240e9
+ ROM @ C2 with a CRC32 of 0x7917b95d
+ Sprite data on a 27C040 EPROM:
+ ROM @ BR1 with a CRC32 of 0x6fc18de4
+ ROM @ BR3 with a CRC32 of 0xbb677240
+
+All EPROMs had identical AFEGA 8, AFEGA 9 or AFEGA 10 labels, so each was named as found
+and are distinguished by PCB / IC locations.
+
+The hotbubla set also has program data with identical halves. While not confirmed, there
+may be a PCB out there using the smaller 27C010's for the program data. IE:
+ ROM @ C1 with a CRC32 of 0x41c3edbc and 0x20000 bytes in length
+ ROM @ C2 with a CRC32 of 0xf59aea4a and 0x20000 bytes in length
+
+It was not uncommon for manufacturers to use whatever size EPROMs were readily
+available and either double the data or padded the empty space with a fill byte.
